  • Control system for regulating exciter power for a brushless synchronous generator
    Patent number: 6909262
    Abstract: 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).
