    Abstract: An overvoltage protection circuit for a vehicle electrical generating system provides a plurality of controlled rectifiers connected to the generator output winding for shunting high transient voltages to ground. A control transistor having a time delay biasing circuit is connected to the field winding excitation circuit for holding the field winding deenergized during the high voltage condition. A single overvoltage detecting device is used to render both the plurality of controlled rectifiers and the control transistor conductive.
