Abstract

An electronic circuit for use with an electrical generator having a voltage regulator which responds to raise or lower control signals to change the voltage output of the generator. The electronic circuit has a circuit for sensing the magnitude of the difference between the voltage output of the generator and the voltage of a bus to which the generator is to be connected. The electronic circuit also includes a circuit for generating control pulses, each control pulse having a fixed maximum pulse duration when the magnitude of the difference is greater than a first predetermined value but which decreases with a decreasing magnitude of difference down to a fixed minimum pulse duration at a second and lesser predetermined magnitude of difference when the magnitude sensed is less than the first predetermined value. The pulses of the minimum pulse duration are generated for magnitudes less than the second predetermined value, whereby the control pulses produce the raise or lower control signals for the voltage regulator to cause the voltage output of the generator to approach the voltage of the bus.
