FOUR POLE NEUTRAL-POINT CLAMPED THREE PHASE CONVERTER WITH ZERO COMMON MODE VOLTAGE OUTPUT

FOUR POLE NEUTRAL-POINT CLAMPED THREE PHASE CONVERTER WITH ZERO COMMON MODE VOLTAGE OUTPUT

A four pole, three-phase, NPC converter that produces virtually no common mode voltage. The low common mode voltage output is achieved by constraining the switch states of the NPC converter. A fourth pole and associated control balance the upper and lower DC link voltages. The converter may be an in...

Zusammenfassung:A four pole, three-phase, NPC converter that produces virtually no common mode voltage. The low common mode voltage output is achieved by constraining the switch states of the NPC converter. A fourth pole and associated control balance the upper and lower DC link voltages. The converter may be an inverter or a rectifier.
