Patent ID: 8629644

Claim:
A fault tolerant DC power system, comprising: a permanent magnet generator (PMG); a first contactor in electrical communication with the PMG; an active rectifier in electrical communication with the first contactor; a second contactor in electrical communication with the first contactor; a motor drive in electrical communication with the second contactor; a third contactor in electrical communication with the active rectifier; a load in electrical communication with the third contactor; and a fourth contactor in electrical communication with the motor drive and the load; wherein the first contactor is configured to sever electrical communication between the PMG and the active rectifier and the second contactor is configured to establish electrical communication between the PMG and the motor drive; and wherein the third contactor is configured to sever electrical communication between the active rectifier and the load, and the fourth contactor is configured to establish electrical communication between the motor drive and the load.
