  • Four pole neutral-point clamped three phase converter with low common mode voltage output
    Patent number: 7920393
    Abstract: 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.
