Abstract:
Systems and methods of fault tolerant power conversion include an inverter with a plurality of inverter phase legs. Each phase leg includes a positive switch, a negative switch, and a bi-directional midpoint switch. Redundant phase leg includes a positive redundant switch connected between the positive switches and the bi-directional midpoint switches. The redundant phase leg includes a negative redundant switch connected between the negative switches and the bi-directional midpoint switches. Upon detection of a fault condition in at least one switch of the plurality of inverted phase legs, one of the positive redundant switch and the negative redundant switch is closed to bypass at least one switch with the fault condition to maintain operation of the power converter.
