    What is interwinding capacitance?

    The following article was originally written by James Tabbi, Deputy Vice President for Exxelia’s Magnetics Business Unit

    Exxelia recently designed an auxiliary transformer for a spacecraft application, where interwinding capacitance was of concern to the customer.  The controller chip they were using in their power supply was noted to be "rather sensitive to excess capacitance."

    Exxelia has also supplied thousands of driver transformers for use in a subsystem of the AN/TPQ-53 Radar System in which interwinding capacitance within the toroidal windings is held to a very demanding tolerance.

    But what IS interwinding capacitance? 

    Capacitance in a transformer winding cannot be avoided. The voltage difference between turns, between winding layers and from windings to the core, creates "parasitic" capacitances in the transformer circuit.  These capacitances are shown as Cp, Cs, and Cw in this schematic diagram of an electronic transformer "equivalent circuit."

    Interwinding and distributed capacitance occur in transformers due to the physical separation of, and electrostatic coupling between, different turns of wire. In general, the capacitance presents itself between the different layers within a winding and between the outside layer of one winding and the inside layer of the next.  

    In conventional magnetics, interwinding capacitance is a function of coil configuration – the geometry of adjacent conductors and separating dielectric media. Specifically, it is directly proportional to the shared surface area of the windings (shown in green and red below), the dielectric constant of the insulator between the windings (shown in gray below), and is inversely proportional to the separation distance through the dielectric media.

    In high-frequency transformer design, leakage inductance and capacitance are often competing design requirements since the beneficial parameters that provide low leakage inductance also tend to increase the interwinding capacitance.

    Excessive capacitance can cause undesirable common-mode noise transmission between transformer windings or between transformer windings and core or another ground connection.

    Exxelia can assist with these design challenges when creating products that have to deal with interwinding capacitance, for all types of magnetic components.  

    Important coil configuration design considerations must be made when capacitive coupling causes unacceptable signal transmission (for example, common-mode noise transmission or undesirable spurious ringing on a high voltage output).  Windings may be configured in a way that reduces the dV/dt voltages induced across dielectric media. Conductive screen(s) tied to preferred potential(s) can also be added between adjacent windings to reduce transmission.

    If you’d like to learn more about interwinding capacitance or would like to discuss your specific magnetics needs with Exxelia, please contact Cover 2 Sales to arrange a call with an Exxelia engineer.

    What is Power Supply Hold Up Time?

    When an AC-DC power supply’s input voltage is interrupted the DC output will only remain within regulation for a short period of time. This is specified on the power supply datasheet as the hold-up time.  During this hold-up time the power supply relies on energy stored in its capacitors to maintain operation.

    Hold-up time is important in certain vertical markets.  The medical industry’s concern regarding hold-up time has increased since the release of the EN 60601-1-2; 2015 (Ed4) immunity standard. Primarily created to address the growing number of products used in home healthcare, this standard specifies multiple AC voltage dips ranging from 20 msec to 5 seconds. The longer outages are addressed by batteries or by designs that ensure no harm will occur to the patient or operator if the power supply output voltage drops out of the regulation band.

    Airborne equipment is covered by the DO-160 standard. Section 16 of the standard refers to power input, simulating conditions of aircraft power from before engine start (using auxiliary ground based power) to after landing, including emergencies. The requirement is for a hold-up time of at least 200 msec.

    In a recent article on their Power Supply Blog, TDK Lambda explores power supply hold-up time:  What it is, where it’s important and, most importantly, several technical approaches for extending hold-up time.  You can read that article here

    If you would like to discuss extending hold-up time in your system, contact Cover 2 Sales so that we can arrange a conversation with a TDK Lambda applications engineer.

    Where and why is a 277VAC input used in the USA?

    The AC power supplied to and used by household and commercial buildings in the USA is primarily 120VAC.  This voltage is suitable for most electrical and electronic equipment in the home or office, but for the higher power requirements of electric driers, air conditioning and electric ovens, 208VAC or 240VAC is also available.

    In larger industrial properties, in addition to 208VAC and 120VAC, 480VAC three-phase is supplied to the building in a "WYE" (or Y) configuration.  Using 480VAC three-phase to power larger electrical equipment like fork lift battery chargers and heavy machinery allows less current to be drawn by the load, thus enabling the use of lighter gauge wire.  In addition, the current is balanced equally in each phase.  This power disctribution scheme improves power distribution efficiency.

    This blog article from TDK Lambda delves further into this topic, explaining how 277VAC comes about and how it’s used in industrial applications.  The article also highlights a few of TDK Lambda’s power supply solutions that are well-suited for use in 277VAC input applications.  You can read the entire blog post here: Where and why is a 277VAC input used in the USA?

    TDK Lambda’s Latest: 1/16th Brick 300W Buck-Boost Converter

    TDK Lambda recently announced the introduction of their 300W, 8A-rated i7C family of non-isolated DC-DC converters. 

    The series offers an input range of 9V to 53Vdc and adjustable outputs from 9.6V to 48V.  Special care was taken in the design of the i7C to ensure a seamless transition from buck to boost operation.

    With efficiencies of up to 97%, power losses are minimized allowing the product to operate and deliver high output power in demanding thermal environments. Under light load conditions, the i7C’s control techniques significantly reduce power dissipation.  A 5mA input current draw is typical under zero load conditions. And the input current can be further reduced to 0.25mA (typ) when the remote on-off is utilized.  This extends the amount of time battery powered equipment can remain functional during periods of non-peak operation.

    For more information on the i7C series – or any of TDK Lambda’s power converters – please contact Cover 2 Sales.

    Mil/Aero’s Needs for Storage: Ruggedness and Data Security

    (Article written by Virtium and originally posted to their website here)

    Designers of military and aerospace electronics have very specific data-storage needs – and those needs may surprise you.

    You’d think data collected by, say, a military jet or satellite during operation, could fill a medium-sized storage server. It’s true that such air- and space-born craft generate significant volumes of data, but what concerns designers most isn’t so much the volume of data that need to be stored but rather how to protect them – both from the elements and from falling into the wrong hands.

    Let’s start with data-storage durability. Data-storage devices in military/aerospace applications are expected to withstand shock, vibration and extreme temperatures, as well as contaminants and all other manner harsh environments. But simple durability techniques such as a thicker drive casings or extra solder just aren’t enough.

    In working with our longtime partners in the military/aerospace-electronics market, we learned that often they require an added layer of drive protection: extra ruggedness. To meet that demand for heightened drive – and data – protection, Virtium developed the XR (for extra rugged) line of SSDs and memory modules. The new StorFly-XR SSDs and DDR3 XR-DIMMS were developed to protect the drives and memory modules in harsh conditions such as extreme temperatures, frequent shock and vibration, exposure to contaminating materials and/or the rigors of the battlefield. This higher level of protection is especially important in manned and unmanned aircraft, command and control centers, reconnaissance systems, and satellites.

    The XR product line’s extra levels of device and data protection are derived from the custom ruggedization of key components such as connectors and screw-down mountings, BGA under-fill and conformal coating that protects against contaminants. With that trio of protection features, the StorFly-XR SSDs and XR-DIMM modules can achieve durability beyond that of MIL-810-compliant solutions.

    While devices like the XR SSDs and DIMMs are highly secure against environmental threats, the data they contain must also remain protected, should they somehow come into the possession of bad actors. That’s where AES-256 encryption comes in. With a 256-bit key size, this encryption specification generates a number of possible combinations – 1.1 x 1077 — that’s nearly impossible to crack. (The StorFly-XR SSDs can also use an optional hardware or software write-protection mechanism directly in the drives themselves.) Learn more about the XR line of products here.

     

    Designers of military and aerospace systems electronics need to be conscious of data-storage capacities; an unnecessarily high amount isn’t just an added expense but it can exact a penalty in terms of the system "real estate" required and the heat they generate. For operating system boot and/or small-footprint applications used for system monitoring and logging, capacities could be as low as 16GB but rarely need to exceed 1TB. Likewise with DIMM modules, 2GB to 16GB are fine for those applications. (Both the StorFly-XR SSDs and XR-DIMMs fall within those capacity ranges.)

    Of course, it’s not just military/aerospace systems that can benefit from highly ruggedized SSDs and DIMM modules; "civilian" applications such as transportation, industrial automation, energy, and those in other potentially harsh settings also can help protect their investment – and crucial data – through ruggedized data-storage devices.

    Whichever the application, a common concern among designers continues to be product availability. To them, device durability, data security and application-ideal capacities mean little if they’re not ensured continuity of their projects’ lives, which can be years, if not decades. But they can rest easy knowing that StorFly-XR SSDs and XR-DIMMs each have a ten-year lifecycle, along with a locked bill-of-materials cost.

    Guidelines for Using Aluminum Electrolytic Capacitors

    Aluminum electrolytic capacitors are used in virtually all types of circuit designs. They are commonly used as filtering devices in power supplies. The following blog post includes a number of guidelines to follow when designing with and using electrolytic capacitors.  The material has been paraphrased from United Chemi-con‘s technical topics published on their web sit e here

    Polarity

    • Aluminum electrolytic capacitors should not be used in AC applications.
    • In DC applications, always confirm the polarity. If the polarity is reversed, the circuit life will be shortened or the capacitor may be damaged. Generally, an intermittent reverse voltage of 1V DC is allowed. Capacitors used in circuits whose polarity is occasionally reversed or whose polarity is unknown require the use of bi-polar capacitors.

    Operating Temperature

    Choose a capacitor whose maximum specified temperature is greater than the operating temperature of the application. This will increase the life of the capacitor. If the temperature rating of the capacitor is less than the temperature of the application, the life of the capacitor will be substantially less than expected or the capacitor could fail catastrophically.

    In general, for each 10 degree decrease in operating temperature the capacitor life will double. Conversely, capacitor life will be halved for each 10 degree increase in temperature as determined by the following life expectancy formula.

    where:
    Lx = Lifetime at actual operating temperature Tx
    Lo = Lifetime at maximum rated operating temperature
    To = Maximum rated operating temperature (°C)
    Tx = Actual operating temperature (°C)

    Ripple Current/Load Life

    The life expectancy of an aluminum capacitor is not only determined by the ambient temperature, but also by the ripple current. The ambient temperature plus the increase in temperature due to ripple current equals the operating temperature.

    Do not apply a ripple current exceeding the rated maximum ripple current allowed for the capacitors as do so will result in shortened capacitor life and may result in the capacitor venting or failing catastrophically.

    In many cases capacitor heating due to ripple current is more severe than ambient temperature stress. An acceleration rate of approximately 2x for each 5-10°C temperature increase due to ripple current. The following formula used to determine life expectancy:

    where:
    Lx = Lifetime under actual ambient temperature and actual ripple current
    Lo = Lifetime under maximum rated operating temperature and rated DC voltage with no ripple
    To = Maximum rated operating temperature (°C)
    Tx = Actual ambient temperature (°C)
    T = Inside temperature increase (°C) by actual ripple current
    K = Acceleration factor, varied from 5 to 10 by product and conditions

    Rated Voltage

    If the applied voltage exceeds the rated voltage of the capacitor, the capacitor may be damaged from an increase in leakage current. When using a capacitor with an AC voltage superimposed on a DC voltage, care must be exercised so that neither the peak value of the AC voltage plus the DC voltage exceeds the rated voltage nor that the minimum AC voltage plus the DC voltage inverts the polarity on the capacitor.

    When capacitors are connected in series, the voltage distribution across the series may not be uniform. This is due to the normal DC leakage distribution and should be considered in the design process by using a higher rated voltage capacitor and/or using balancing resistors in parallel with each series capacitor.

    Insulation

    General purpose aluminum electrolytic capacitors are covered with a sleeve made of polyvinyl chloride or similar material. In addition to the insulating properties, the sleeving is also used for marking.   The aluminum can is not insulated from the cathode, and when the internal element needs to be electrically insulated from the can, capacitors specially designed for these insulation requirements should be used. Also, the dummy terminal is not insulated from the cathode and must not be connected electrically to the anode or cathode.

    Soldering

    Incorrect soldering may shrink or break the sleeving of the capacitor. Please read the following information carefully before soldering:

    1. If the soldering iron comes in contact with the capacitor body during wiring, damage to the polyvinyl sleeve and/or case may result in defective insulation or improper protection of the capacitor element.
    2. When soldering a printed circuit board, care must be taken so that the soldering temperature is not too high and the wave or soldering time is not too long. Otherwise, there will be adverse effects on the electrical characteristics and the insulating sleeve of aluminum electrolytic capacitors. In the case of miniature aluminum electrolytic capacitors, no harm will occur if the soldering process is performed at less than 260°C for less than 10 seconds.
    3. During soldering, the sleeve may melt or break if it comes in contact with the circuit board traces. To avoid this problem, do not locate circuit board traces under the capacitor body.
    4. The sleeving may be melted by solder which migrates up through the terminal holes in the circuit board. To avoid this problem, the same application as stated in item 3 is recommended.
    5. When soldering adjacent components to the capacitor, preheated lead wires or terminals may tear the capacitor sleeve if these terminals come in contact with the capacitor sleeve. Therefore, mount the capacitors carefully so that the adjacent components’ terminals or lead wires do not come in contact with the sleeve, particularly when mounting on through-hole circuit boards.

    For surface mounting capacitors, the reflow soldering conditions are specified in the Surface Mount section of United Chemi-Con’s catalog.

    If you have any questions about electrolytic capacitors, please contact Cover 2 Sales for assistance!

    An Introduction to Aluminum Electrolytic Capacitors

    Capacitors. So many different types and technologies… but why? What’s unique about them? This blog post attempt to answer those questions about one of the most common capacitor technologies: the aluminum electrolytic capacitor.

    The aluminum electrolytic capacitor is a passive component that has traditionally been used for filtering, timing networks, by-pass, coupling and other applications requiring a cost effective, volumetrically efficient and highly reliable component.

    An aluminum electrolytic capacitor consists of an anode foil, a cathode foil and separator paper which are wound together and impregnated with an electrolyte. The anode foil has an aluminum oxide layer acting as the dielectric. After the thin aluminum foil (65 to 100 microns) is electrochemically etched to increase the plate’s surface area, the dielectric is produced by anodic oxidation on its surface. The cathode foil, in general, utilizes no oxidation process.

    Note that due to the physical design elements and construction, not only does a capacitor have capacitance, but it also has a series resistance and inductance as well as a parallel resistance allowing the flow of current.

    The capacitance of aluminum electrolytic capacitors (in microfarads) is expressed by the following equation:

    C = 8.855 x 10e-6 x (ES/d)

    E = Dielectric constant
    S = Surface area of dielectric (cm2)
    d = Thickness of the dielectric (cm)

    Large capacitance can be obtained when:

    • the dielectric constant is high
    • the surface area is large
    • the dielectric is thin

    In aluminum electrolytic capacitors the dielectric constant is only 8 to 10, but the aluminum oxide dielectric layer is extremely thin (about 15 Angstroms per volt).  High gain foil produced by the electrochemical etching creates a surface magnification, or gain, as much as 100 times for low voltage foil and 20 to 25 times for high voltage foil.  Therefore (and this is a critical benefit of these capacitors):

    An aluminum electrolytic capacitor can provide a large capacitance compared to other types of capacitors of the same volume

    Nippon Chemi-Con – the parent company of United Chemi-Con – is the world’s largest manufacturer of aluminum electrolytic capacitors. NCC pioneered the development of raw material processing techniques and highly automated production systems. The product improvements of these innovations have dramatically improved circuit design flexibility and led to many new applications for aluminum electrolytic capacitors.

    Quell’s U.S. Frequency Allocation Chart

    The recent growth in wireless communications is staggering and, as a result, there are innumerable users of the radio frequency (RF) spectrum. To prevent interference between users, the United States has defined regulations for the transmission of radio waves in various frequency bands. Some frequency bands are reserved for public and government uses. Others are licensed to operators of communications services, like broadcast TV and cell phones. And other bands are unregulated and available for public use.

    If your vocation or avocation has you working or playing in the radio frequency spectrum, keeping track of the various frequency allocations is critical. There are thirty different types of radio services and the allocations are often changing as new technologies are developed.

    Quell Corporation has developed a chart of the United States’ frequency allocation to map the uses of all of the US frequency bands and their users. The chart covers frequencies from 0Hz to 300GHz.

    What is a Cover 2?

    From the time Cover 2 Sales first opened for business in October of 2003 the question has regularly been asked: “What is Cover 2?”

    The Cover 2 is a style of defense in American football. It’s a zone defense in which every defender is responsible to cover a specific area of the field. It’s typically used in pass defense situations. Two safeties play well back from the line of scrimmage. They divide the field in two, with each safety covering half. Hence, the “cover 2”. The remaining defenders provide coverage underneath the safeties, with the cornerbacks handling the sidelines and linebackers covering the middle. Defensive linemen (those that are not rushing the passer) can drop into shallow coverage to defend against short passes. While there are numerous variations of the Cover 2, in its’ purest sense the Cover 2 is a zone defense, with each player responsible for a specific territory.

    When play begins, each player keeps his eyes on the ball and stays aware of what is happening in his territory. When an opportunity comes his way, the player reacts quickly and confidently to produce the desired results for his team. The Cover 2 works best when it’s staffed with high-energy personnel that have a firm understanding of their territory, can identify opportunities coming their way and can close quickly and confidently. When properly executed the Cover 2 is unbeatable.

    Cover 2 Sales brings the same philosophy to sales. Staffed with ambitious, experienced, technical sales representatives, Cover 2 Sales offers the Chesapeake region unparalleled coverage. Cover 2 Sales truly is the unbeatable manufacturers’ representation option!
