A plurality of generators redundantly supply power to AC motors via a main DC bus system having a pair of buses, each of which is connected to each generator by an active front end (AFE) inverter containing an insulated-gate bipolar transistor. Isolated DC/AC inverters are connected to the pair of main buses in pairs, respectively. Each pair of the isolated DC/AC inverters is connected to one of the AC motors with a filter of capacitors and inductors between each inverter and the motor. The AFE inverters and isolated DC/AC inverters galvanically isolate the main buses and enable load sharing among the generators.
