Optimization of large scale power electronic structures for comfort electronics in passenger vehicles

In this paper the situation concerning electric loads and the corresponding power electronics in passenger vehicles is described based on an analysis of an upper mid class vehicle. The large number of loads and semiconductor devices demand alternative structures to operate the loads. In this paper an alternative structure is presented, which can reduce the number of power semiconductors. This structure needs to be optimized. This paper describes the optimization methods used and presents some optimization results
