Abstract: The regulator includes a control circuit for controlling a transistor switch. The switch has an output coupled to a field terminal which is to be coupled to the rotor's field coil. The regulator also includes a stator terminal coupled to the control circuit; an ignition terminal coupled to the control circuit for turning the regulator on and off; and a positive battery terminal coupled to the control circuit. A bank of capacitors is coupled between the stator terminal and the input of the switch. The rectifier has an anode coupled to the battery terminal and a cathode coupled to the input of the switch. The capacitor bank in conjunction with the rectifier boost the voltage to the switch and the field. This increases the maximum output of the alternator.
