Abstract: PURPOSE: To avoid sudden changes in the resistance torque of an internal combustion engine, when an exciting current applied to the armature winding of a generator is changed by the change of an electrical load, etc., in the recharging system of a vehicle battery. CONSTITUTION: The collector and emitter of a drive transistor (17) are connected in series to a field winding (5), and both the terminals of a battery (1) which is the supply source of a DC voltage (VBA). A sensor means (19) which detects a current applied to a field winding (4) is provided. Control circuits (10-16), which control on/off of the drive transistor (17) according to a value which is determined by comparing a voltage (VA) supplied by a generator (2) with a comparison voltage, depending on a current detected by the sensor means (19), are provided.
