ABSTRACT:
A control system for a self-excited alternator which includes an auxiliary winding adapted to supply excitation to the alternator field winding incorporates a circuit for supplementing field excitation when the available energy from the auxiliary winding is less than the desired magnitude of field excitation. The self-exciting a-c current from the auxiliary winding is coupled through a phase-controlled rectifier circuit to the alternator field winding. A secondary excitation source such as a battery is coupled to the alternator field winding through a chopper circuit. A regulating circuit is responsive to a field current reference signal for controlling the conduction of the phase controlled rectifier circuit and the chopper circuit in a manner to regulate the alternator field excitation to the desired value. The regulating circuit is adapted to supplement the excitation supplied by the auxiliary winding with excitation from the secondary source until the excitation available from the auxiliary winding is sufficient to supply the desired magnitude of alternator field excitation.
