Abstract

A previously proposed traction converter topology can reduce component effort and converter volume by decreasing the pulsed voltage across the DC-converter inductance. However, the maximum voltage across the machine phases then becomes a function of the DC source voltage. In this paper, an optimization is presented to ensure a constant maximum phase voltage over a wide source voltage spread.
