The requirements profile in automotive is characterized by the absence of a standardized mission profile for APE engineering, but several test cycles exists which are used for fuel consumption- and emissions measurement of vehicles. Based on a NEDC test cycle a first approach that may be used as a basis for a design optimization the DC-link function in a HEV power train converter will be explained, and the application benefits of the PCC concept will be shown. The integration friendly new developed capacitor technology offers voltage ratings up to 1000 VDC, maximum Volume Fill factor (VFF) and for PP dielectric a STO-temperature up to 125 deg C. The dimensional flexibility of PCCs allows customized designs and satisfies hitherto unfeasible size requirements and PCCs delivers outstanding performance data like low ESR and ESL values - mainly due to integrated busbar designs. The capacitor range is starting now with the well known small stacked capacitor sizes up to big PCCs in power cap format including circular designs corresponding to in the gear bell area integrated 2nd generation HEV converters. The development trend is characterized due to the fact to put its emphasize on the most efficient electric drive which in turn demand of compact low loss and cost effective power capacitors. The HEV motor output Pm rose from the level of 20 kW to 30 kW in 2001 up to 140 kW in 2006, the rated voltage Vr started at 100 VDC to 300 VDC and has reached Vr about 750 VDC and the capacitance values ranging now from 500 microF up to 3000 microF. Modern HEV converter design strategies trying to find alternative options for the once popular Electrolytic Caps which had the advantage of high CV values for Vr below 450 VDC; the choice now rests with film- and metallized PP capacitors in particular.
