Abstract
A control for a brushless generator operable in starting and generating modes supplies combined AC and DC power to an exciter field winding of the brushless generator during operation in the starting mode. The magnitude of a parameter of the AC power is decreased with increasing rotor speed during operation in the starting mode until a particular rotor speed is reached, following which only DC power is supplied to the exciter field winding.
