Abstract

See full text

A fault tolerant generator apparatus includes subsystems isolated from each other, so that the generator may operate in a fault mode with low torque ripple. The apparatus comprises a machine and a power controller unit. In an embodiment, the machine has a plurality of electrical three phase windings and the power controller unit has a plurality of power converters. Each three phase winding of the machine is coupled to a separate corresponding power converter to form an operating subsystem. The operating subsystems are physically and electrically isolated from each other to provide fault tolerant operation of the apparatus. Accordingly, each of the operating subsystems is effective to provide a balanced electrical load for the machine.
