Abstract :
The paper presents circuit topologies for medium voltage converters and investigates their suitability for high voltage low power applications with up to 4 MVA. For an example of an inverter for 6 kV motor voltage the four level floating capacitor topology was chosen. Advantages of this topology are the balanced power dissipation of the power semiconductor devices and direct voltage clamping of each power device. Details of the motor inverter design are presented
