Abstract

An electrical energy supply system (12) comprises an input rectifier (14) for rectifying an input voltage into a DC voltage an inverter (18) with semiconductor switches for generating an AC output voltage from the DC voltage and a controller (24) for switching the switches of the inverter (18). The inverter (18) is adapted for generating a 5 level AC output voltage. The controller (18) is adapted to switch the semiconductor switches such that an asymmetric pulse shape is generated from the inverter (18) in a half cycle of the AC output voltage.
