A control system regulates power to a brushless synchronous generator (BSG) (204)
having a permanent magnetic generator (PMG)(210), an exciter (208)
and a main generator (206) connected to a rotating shaft (212). The
generator control unit (GCU) (202) includes a three phase rectifier (214),
a PMG voltage regulator (222), a generator control relay (GCR)(220),
a GCU power supply (216) with a backup power source (217), a field
switch driver (218), a field switch (219), and a free wheeling diode
(221). The BSG (204) is connected to the GCU (202) by coupling
the PMG (210) of the BSG (204) to the three phase rectifier (214)
of the GCU (202) and by coupling the exciter (208) of the BSG (204)
to the PMG voltage regulator (222) and the field switch driver (218)
of the GCU (202) and the PMG voltage regulator (222) regulates the
voltage of the PMG (210).
