Abstract
The circuit includes sensors for supplying electrical signals indicative of the current flowing in the field winding of the generator in operation and a control circuit operatively connected to the sensors. The control circuit is arranged to control the transistor which drives the field winding so that the voltage at the battery terminals remains substantially constant with variations in the current supplied to the battery by the generator.
