Claims12
A brushless wound field synchronous generator configured to generate an output power to drive an electrical load, the wound field synchronous generator comprising:
- a main generator portion with an armature winding and a field winding rotatable with respect to the armature winding and an exciter portion, the exciter portion including a field winding and an armature winding rotatable with respect to the field winding;
- and
- a rotating rectifier assembly disposed between the exciter portion of a rotating armature winding and a main generator portion rotating field winding, the rotating rectifier assembly configured to generate a direct current (DC) voltage to provide the DC voltage to the main generator portion rotating field winding, the rotating rectifier assembly including a rotating diode assembly and a field effect transistor (FET) to control voltage across the rotating diode assembly.
A rotating rectifier assembly, comprising:
- a rotating diode assembly including a plurality of diodes to form a voltage rectifier circuit configured to generate a direct current (DC);
- and
- a field effect transistor (FET) to control voltage potential realized across the voltage rectifier circuit in response to the voltage potential exceeding a predetermined threshold voltage level.
