ABSTRACT:
A brushless exciter for a synchronous generator or motor generally includes a stator and a rotor rotatably disposed within the stator. The rotor has a field winding and a voltage rectifying bridge circuit connected in parallel to the field winding. A plurality of firing circuits are connected the voltage rectifying bridge circuit. The firing circuit is configured to fire a signal at an angle of less than 90° or at an angle greater than 90°. The voltage rectifying bridge circuit rectifies the AC voltage to excite or de-excite the field winding.
