In modern applications of power electronics, AC capacitors are among the most critical links in the chain of components when it comes to long operating life, safety and reliability of operation. Decades of proprietary ELECTRONICON experience in metallizing capacitor films and designing high-end capacitors have created our very own Know-How, for instance in special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. This enables us to design AC capacitors with a high specific ratio of capacitance to volume, high AC-voltage load capacity and outstanding suitability for high rms and surge currents. The cylindrical capacitors of our universal AC/DC series "E62" are perfect for non-sinusoidal voltages and pulsed currents, e.g. as damping or commutation capacitors switched in parallel to a thyristor, or connected in series with a resistor (damping of undesirable voltage spikes during the switching of power semiconductors).

The winding elements in our MKP(D) capacitors are surrounded by poison-free vegetable oil. Like our premium ranges of MKPg and MKP, the MKP(D) combines the best possible technical features with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our MKP(D) capacitors distinguish themselves by high AC-voltage load capacity and suitability for high rms and surge currents. Our MKP(D) are available as single and three-phase capacitors and well-suited for all conventional applications in power factor correction. They have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM "). Connection is made through convenient standard 6.3mm tab connectors. Technical layout, testing and application accord to IEC60831, UL810 and CSA 22.2.

With our long year know how and first-class production facilities, we are manufacturing capacitors in two basic technologies: MKP and MKPg™. In MKP capacitors, the winding elements are surrounded by poison-free vegetable oil, in MKPg™, capacitors, they are immersed by neutral insulation gas. When designing our product ranges, we focussed on the best possible technical features combined with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our power capacitors distinguish themselves by high AC-voltage load capacity and outstanding suitability for high rms and surge currents. Unlike some of our competitors who proudly quote fantasy ratings, we have really tested our capacitors to their rated values, allowing for sufficient reserves and guaranteeing flawless operation within the specifications.

The custom-tailored capacitors of our E70 series are mainly applied for power factor correction or as resonance capacitors in induction furnaces that are operated at mains frequency (50/60Hz). The E70 are made alternatively in two designs: Inside the steel case, there is a large number of individual self-healing capacitors, each one of them protected by its own break-action mechanism. In the event of a failure, the affected element is disconnected separately while the capacitor as a whole continues to function with slightly decreased total capacitance. Windings assembled inside a hermetically sealed metal case, filled with solid resin, and protected by a pressure sensor similar to the capacitors of our ranges E56/E59.

The special kind of films and coating patterns used in our oil-filled E63-capacitors give them a high specific ratio of capacitance to volume and makes them extremely overvoltage proof. Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life. Hence the E63s are interesting particularly for applications with high AC ripple currents, e.g. as smoothing or supporting capacitors in buffer storage circuits, in sensitive environment with high safety requirements. Note that the presence of an overpressure mechanism adds substantially to the self-inductance of the capacitor, and limits the surge current rating. If self-inductance and surge current are important issues, then our E50 or E53 ranges may be considered as a more adequate option.

It works - even in your smaller DC links! A few years ago, our PK16TM pioneered the large-scale shift from batteries of electrolytic DC link capacitors to energy-efficient and highly reliable film capacitors which has become so common nowadays. The E61 range makes the benefits of this substitution available for DC links with smaller powers now. With their pin terminals, these capacitors can be integrated directly into your printed circuit board. The capacitors of the E61 series are optimized for high rms and surge currents. Along with their high specific ratio of capacitance to volume, they offer long-term stability and storability, as well as excellent self-healing without loss of capacitance. It is our advanced know-how in special capacitor film coating, combined with many decades of practical experience in designing and manufacturing capacitors, which have allowed us to develop this range with its numerous advantages over traditional electrolytic capacitors:

E57 are designed to fit directly to the terminals of your IGBT. Our range comprises standard as well as custom-tailored solutions which can be adapted to the specific geometrical and electrical requirements of your application environment. Connection is made through low-inductance copper bars which may vary in number, size and position according to your specifications. The UL:V0 plastic case houses compact and stable cylindrical windings, connected in parallel for maximum current strength and lowest possible selfinductance; it is filled with polyurethane resin, covered by a layer of UL94:V0 compliant resin protecting the winding package from humidity. Our highly reliable SecuMet™ film guarantees secure self-healing properties even under the most demanding operating conditions. Some of our E57 capacitors can be operated at ambient temperatures up to 105°C and are therefore suitable for usage in automotive and other critical applications

The capacitors of our SR17™ series were developed especially for the maintenance of older traction converters manufactured in the 1970s?1990s. By consequent development of our well-proven MKP-technologies, we managed to place self-healing DC-capacitors with very high energy density and stability of capacitance into can dimensions smaller than, or identical to, those of the traditional MP-capacitors (SIEMENS/EPCOS codes B25353), which makes them ideal drop-in replacements for maintenance and retrofit programmes. Moreover, the low-loss polypropylene dielectric permits a far higher AC ripple load than with the conventional MP-capacitors. Our SR17™ are housed in a hermetical stainless steel cylinder. As opposed to the oil-filled MP-models, these are filled with an eco-friendly solid resin which does not only make them safe against leakage of liquids but also insensitive to the shocks and vibrations common in traction applications. The same applies to their robust plastic insulators.

Thanks to the special kind of films and coating patterns used in our E56/E59-capacitors, clever winding geometries and refined internal construction, they unite large capacitance, very small self-inductance and high surge current sustaining capability (up to 700kA) as well as the possibility of high rms currents (up to 750A). Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress and instabilities at the edges of flat packs. Special terminals allow for additional reduction of the self-inductance. At the same time, they are extremely overvoltage-proof. They are especially suited for buffer storage circuits of converters, filter circuits and such like. The capacitors are housed in aluminium or steel cases and filled with solid resin which makes them absolutely dry and leakage-proof. Their shape and dimensions can be adapted to the individual requirements of our customers.

The PK16™ capacitor can be universally used for the assembly of low inductance DC buffer circuits and DC filters; with its high energy density it can replace banks of series-connected electrolytic capacitors as well as large film capacitors in rectangular cases. The capacitance in a DC buffer circuit must be sufficiently sized to both handle and smoothen the occurring ripple currents. The traditional use of series-/parallel-connected electrolytic capacitors offered large capacitance at seemingly low cost, however the low cost per microfarad is countered by the very low current strengh, the high sensitivity to voltage and current surges, as well as a substantial risk of failures in the field, resulting in high maintenance cost. Our advanced know-how in special capacitor film coating and many years of practical experience in designing and manufacturing capacitors have allowed us to develop our PK16™ range with high capacitance density.

Using selected low-loss, self-healing polypropylene films and sophisticated manufacturing techniques such as high-vacuum drying and special coating patterns, the best of ELECTRONICON™s design expertise and highest care in manufacturing have been spent to prepare these capacitors for your most demanding applications, and toughest ambient conditions. Our long-life MKP UHDTM contain three delta-switched capacitor elements of short height and large diameter. The optimized combination of winding length, film size, and winding geometry substantially reduces inherent power losses and allows us to achieve highest surge and rms current ratings as well as an overvoltage strength and switching stability which before would have been known only of impregnated paper capacitors. An MKP UHD™ handles up to 250% of its rated current and current surges of 400 x IN. The permitted operating temperatures range from -40°C up to 70°C maximum temperature (average over 24 hours: 60°C).

Who said it has to look like a surge capacitor? They look different, and as a matter of fact, they are. Surge protection capacitors are designed to protect high voltage motors and transformers from events with high transient overvoltages (e.g. lightning or switching surges). Keeping with our tradition of completely dry products, we have designed the first MV Surge Capacitor in self-healing technology: DSCTM In combination with the PD-free layout, the self-healing dielectric provides for extremely long operating life and highest operational safety. Unlike traditional oil-filled ALLFILM-capacitors which are bound to fail as soon as overvoltage or other stress factors have provoked a dielectric breakdown, the self-healing dielectric of DSCTM insulates the breakdown spot immediately and continues operation as usual.

The E62-3ph capacitors stand out by their high AC-voltage load capacity. They have been designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion, a.m.o. Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength. The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation.

AC capacitors require a hermetical casing in order to operate safely and without processes of chemical corrosion. The latter would result in deterioration of metal coating, decrease of capacitance as well as rise of loss factor and – consequentially – failure of the capacitor. DC capacitors – even though less sensitive to humidity – may suffer from excessive operating conditions as well. Another serious issue is the operation in conditions of extreme heat, and there are situations where placement in a cooling liquid is the only way. Certain high voltage applications may require the immersion of all components in insulation oil, such as MIDEL. Quite a few cooling or insulation oils behave aggressively towards metallized polypropylene, causing swelling of the film and deterioration of the contact layers. They must therefore be kept away from the capacitor elements. In the past, mostly MKV capacitors (with oil-impregnated paper electrodes) had to be used in such situations.

E53 and E55 capacitors have a particularly low series resistance and high pulse strength. Using sophisticated metallizing patterns, our SINECUT slitting technology and clever winding geometries, they are especially suited for the damping of GTO thyristors and low-inductance buffer circuits with high rms currents. Along with their very good ratio of capacitance to volume, these components do also have very good self-healing characteristics without loss of capacitance. Their very low self-inductance makes them suitable for use in high-current applications with medium frequencies. The capacitors of the E53 product family are housed in flame-retardant plastic cans (V0) and filled with solid resin. Special care has been taken both in terms of design and conservative electrical rating to ensure reliable operation even under tough environmental conditions. Connection is usually made through robust axial terminals with internal thread.

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance and creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor. Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread.

Our capacitors of the E12 and E33 series are universally-suited for lighting and motor applications as well as power factor correction and power electronics. Their winding element of self-healing polypropylene film is immersed in eco-friendly vegetable oil and designed for highest requirements regarding operational life and functional safety even at high operating temperatures and other extreme conditions such as high humidity. Connection is made through tab connectors. The hermetical aluminium can is provided with an integrated overpressure safety mechanism (break-action mechanism, " BAM ") that disconnects the capacitor irreversibly from the supply in the event of a failure. The E12/E33 ranges comply with the "Type B" classification under lighting standard IEC/EN61048 as well as with "Class P2" under motor capacitor standard IEC/EN 60252-1. Please mind our safety remarks on the use of lighting capacitors in critical environment.

Harmonic distortion is a key issue not only in low voltage, but also medium and high voltage Power Factor Correction. The installation of detuning reactors helps to protect capacitor installations from dangerous and devastating resonances by preventing any amplification of harmonic currents and voltages caused by resonance between capacitors and inductances in the mains. At the same time, it reduces the overall level of harmonic distortion in the mains. With FKD-MVTM, we are now expanding our long-year experience in making reactors for low-voltage PFC to the field of medium voltage up to 10kV. The low-loss reactors which are made of aluminium windings on iron cores, are optimized for use with our MSDTM capacitors. Each reactor is formed by a set of three compactly sized single phase units; that makes handling easier during mounting and maintenance and opens interesting options for allocation and dimensioning of your equipment.
