The system (16) has an inverter (30) e.g. neutral point clamped (NPC) inverter, connected to an output of a rectifier (26) e.g. active front end rectifier, via a direct voltage bus (31). The inverter converts the direct current (DC) provided by the rectifier into the alternating current (AC) deliver...
