Abstract

The growing spread of electric vehicles in any performance class is leading to stricter safety requirements for theelectric powertrain and increasing DC-link voltages for high-powered vehicles. Thus, fault-tolerant topologies suchas the ANPC converter are coming into focus. Nevertheless, especially in the automotive industry, an ideal electricpowertrain must combine high reliability, high efficiency and low cost to be competitive. Therefore, this paper presentsan analytical approach to determine the efficiency and overall cost of an ANPC converter for different modulationstrategies and a comparison with a state of the art two-level B6 converter.
