Abstract

A generator control circuit is disclosed. One embodiment provides a first active switching circuit configured to connect a first terminal of an excitation coil either to a first or to a second terminal of a voltage source, a second active switching circuit configured to connect a second terminal of the excitation coil either to the first or to the second terminal of the voltage source, and a generator controller to set the duty cycle of the active switching circuit to rapidly control the current through the excitation coil to an excitation coil current setpoint.
