To extend the application of insulated gate bipolar transistor (IGBT) inverters in motor drives to higher voltages, a three-level IGBT inverter has been developed. The power circuit realized and a pulse pattern generator with space voltage modulation are described. A method to control the middle point potential is suggested. The three-level IGBT inverter can be applied to industrial drives with a three-phase supply voltage of 660 V and drives for local traffic with DC line voltage of 600-750 V.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
