Abstract
A conventional on-off voltage regulator operates a set of power MOSFET switches interposed between the grounded terminal of the battery and each of the diodes of a bridge rectifier leading to that terminal. Each such switch is controlled through an individual circuit responsive to the regulator output and including an opto-electronic device controlling a thryistor which, in addition to being connected to control the MOSFET switch, also has a connection through a resistor and a diode to the other side of the rectifier diode switched by the MOSFET. The circuit greatly simplifies voltage regulation of a battery charging system using an alternator with a permanent magnet rotor.
