ABSTRACT:
A control apparatus for controlling the power supply to the field coil of a charging generator in which a smoothing capacitor of a low capacitance value is provided to prevent maloperation in the control circuit due to ripples in the output of the generator. A switching transistor controls the current flow through the field coil, while a control transistor controls the switching transistor and a zener diode is provided for energizing the control transistor. A first detection circuit is connected to the smoothing capacitor for detecting the rectified output of the generator and thereby producing a voltage at a first detection point. A second detection circuit produces a voltage at a second detection point which is higher than the first detection point voltage. An amplifying transistor having a base connected to the first detection point energizes the zener diode in accordance with the state of the output of either of the first and second detection circuits.
