Abstract：The main considerations of selecting DC link capacitor of motor driver and shortages of conventional designs for electric vehicles were analyzed. The PSpice model of VSI with major parasitic parameters was developed based on advanced film capacitor. These parasitic parameters were considered for the precise analysis of the DC link capacitor selection and the transient operation of IGBT. FLUKE PM6304 programmable automatic LCR meter was chosen as the tool for parasitic parameters measurement. Finally,an 80 kW drive VSI with film capacitor was set up. Simulation and experimental results show that the main consideration factor of selecting DC link capacitor is its ripple current handling capability. The VSI with reduction of DC link capacitor has a volumetric power density of 13 kW/L and a peak power of 11 kW/kg.
