Abstract
A system includes a generator control unit (GCU). The GCU includes a first rectifier and a second rectifier. Each of the first rectifier and the second rectifier has a separate input to receive AC power from a separate respective permanent magnet generator (PMG). A method includes supplying AC power from a first PMG of a variable frequency generator (VFG) to a first rectifier of a generator control unit GCU that is operatively connected to control the VFG. The method includes supplying AC power from a second PMG to a second rectifier of the GCU. The first PMG supplies a lower AC voltage to the first rectifier than the second PMG supplies to the second rectifier.
