Abstract

In this paper the power losses of an AC/DC-converter for an electric vehicle drive are analyzed. A validated model which calculates the losses analytically based on forward parameters and switching losses maps is used to design two converters, one for a standard machine and another for an energy efficiency optimized machine. With this a losses reduction of 25% can be achieved, just in the power electronics. Furthermore, two different IGBT generations are compared and a losses reduction of about 19% can be reached with the new IGBT3. Both reductions can mostly be derived from improvements of the switching losses.
