Epcos is working with Continental Temic on the development ofcomponents for power electronics in hybrid vehicles. In theElectronic Powertrain Controller (EPC) Project, Continental Temicis using capacitors based on Epcos' innovative stackedwinding technology to produce extremely compact and efficientconvertors for automotive power trains.

The extremely light andspace-saving design of Epcos power capacitors enables therealisation of ultracompact designs in automotive electronics.Rated at 2000uF, the power capacitors have a dielectric strengthof 450V DC.

Thanks to their space-saving stacked windingtechnology, they measure only 292 x 146 x 56mm.

At an operatingfrequency of 8kHz, a current up to 150A RMS can be applied to thecapacitor.

In turn, the very low-inductance capacitors optimiseconvertor design because only low voltage peaks, for example, canoccur.

Further advantages of the capacitors include theiroil-free design and self-healing capability.

A wide operatingtemperature range extends from -40 to +105C.
