Zero-voltage switching power converter

Abstract

The zero-voltage converter is able to perform at extremely high power levels and bares significant benefits to all levels; system, inverter and circuitry level. Power losses are avoided by using a new developed resonant topology. EMI problems are reduced by power module integrated capacitors as well as smart selection of the terminal technology and under full utilization of the analog components and their potentials. The power module developed for this specific application is designed under a maxim of gaining highest power density as well as lowest stray inductances. High switching frequencies enable even special electro motors with extremely low leakage inductance to perform well. This is in particular beneficial for ultra high speed drives or motors with a high pole pair number. The mechanical concept of the inverter can specifically be adopted to the referring vehicle and to its available installation space. Thus, also (hybrid) electrical vehicles can be designed based on such highly innovative conception.
