Inverter loss minimization for a plug-in hybrid veihcle traction drive using DSC control

Abstract

Plug-in hybrid electric vehicle can be very useful to improve fuel economy and reduce the level of pollution especially in the urban area. This kind of vehicle needs a large battery stack to assure a good autonomy distance range in pure electric (zero emission) operating mode. To make this possible the dimension and the efficiency of the whole power train have to be optimized. The inverter in the electrical traction drive is one of the key component in the power train. In this paper a method for evaluating and reducing the inverter losses has been presented.
