Abstract
In common applications electric drives mostly do not operate at full but at partial load. Concerning the energy efficiency of the electric drive not the maximum efficiency is essential but the efficiency at low load is relevant. In this paper a new method is presented which improves the efficiency of the power electronics of an electric drive at partial load. The method is based on a variation of the active transistor area. In case of an electric vehicle a power losses reduction of about 15% can be reached just in the power electronics in the driving cycle ARTEMIS ROAD.
