ABSTRACT:
A permanent magnet generator system is provided with a permanent magnet generator having a multiple phase armature that includes several circuit branches which are electrically connected to provide a multiple phase output voltage to the output terminals of the generator. At least two of the circuit branches include an armature phase winding and a switching device electrically connected in series with the winding. The switching devices are opened and closed in response to a control signal to disconnect the generator from the remainder of the electrical system and to simultaneously de-energize the individual phase windings of the generator armature to protect against a fault occurring within the generator housing.
