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.

Claim (Index 19):
A method of fault tolerant operation of a T-type power converter comprising:\n providing a T-type power converter comprising:\n a DC-us comprising a DC-bus midpoint and three inverter phase legs operatively connected to the DC-bus, each phase leg comprising a positive switch, a negative switch, and a bi-directional midpoint switch; \n a redundant phase leg comprising a positive redundant switch and a negative redundant switch, the positive and negative redundant switches connected in series with the bi-directional midpoint switches through a redundant midpoint, the positive redundant switch connected in parallel with the positive switches through the bi-directional midpoint switches, the negative redundant switch connected in parallel with the negative switches through the bi-directional midpoint switches, and a bi-directional midpoint redundant switch connected between the DC-bus midpoint and the redundant midpoint; \n monitoring at least one current within the T-type power converter with a microcontroller; identifying a fault condition in the T-type power converter based upon the at least one current; determining a switch location of the fault condition based upon the at least one current; upon detection of the fault condition, switching the bi-directional midpoint redundant switch to an open condition and operating at least one of the positive redundant switches and one of the negative redundant switches to a closed condition to bypass the switch location of the fault condition; and maintaining operation of the T-type power converter.
