Abstract


In this paper a precise and simple methodology will be introduced for modeling and calculating the Voltage Source Inverter (VSI) losses in Hybrid Electric Vehicles (HEV) application. The noteworthy traction inverter losses, consisting switching and conduction losses of diodes and IGBTs, are important for evaluating the overall efficiency and obtaining the optimized value of its dc-link voltage as well. For this purpose, the effects of different battery voltage levels on the inverter losses are examined.
