摘要

As demands from the international community intensify for lower emissions vehicles,rnautomotive manufacturers must balance future technological innovation with the traditionalrnperformance, comfort, and cost expectations of today’s consumer. Development by thernautomotive industry has focused on the “Hybrid Electric Vehicle” (HEV) as the concept ofrnchoice. The HEV is preferred for its utilization of a smaller internal combustion enginernunder continuous light duty and an electric motor for back up during heavy load conditions.rnThe key to meeting these well established consumer expectations is the design innovation ofrnthe HEV’s support system designs. One such example is the new “Integrated Starter andrnAlternator” (ISA). The ISA consists of both an “Idling Stop/Start” system and an “EnginernAssist” system for heavy load conditions. Two key technologies behind these systems arernthe “Motor/Generator” and “Inverter”. These devices must not only become smaller but alsornachieve higher output power capability as compared to present technology. In addition, theyrnmust also be resistant to high temperature mounting direct to the combustion engine isrnrequired. Particularly critical for determining the inverter’s size and performance are thern“Power Semiconductors” and “Power Capacitors”. The focus of this paper will be on thernrequirements necessary for the improvement of the “Power Capacitors”.
