Abstract: Systems and methods are provided for dynamically changing configurations of multi-inverter drive systems. By changing configurations during operation, a multi-inverter system of the present invention can provide greater than half of full output power during failure of a power cell and can provide efficient braking torque during regeneration. The inverter drive system includes a plurality of single pole inverter cells and a configuration switch system connecting the single pole inverter cells in a star configuration and for changing the connection configuration of the single pole inverter cells. In one embodiment, the configuration switch system is adapted to dynamically change the star configuration of the inverter system to a mesh configuration during operation of the load. In another embodiment, the configuration switch system is adapted to dynamically change the star configuration of the single pole inverter cells to form a polyphase inverter.
