Abstract
A voltage regulator for use with a polyphase magneto generator and in combination with a rectifier circuit provided to rectify the output of the generator to charge a battery, comprises at least two thyristors having the anodes respectively connected to the output terminals of the generator having phases adjacent to each other, having the cathodes connected to the negative output terminal of the rectifier circuit, and having the gates connected to each other. A trigger device is adapted to supply gate signals to the gates of the thyristors when the voltage of the output terminal having a phase in advance of the phases of the output terminals to which the anodes of the thyristors are connected exceeds a predetermined value. As the battery terminal voltage is excessive the thyristors are rendered conductive to short-circuit the output of the generator.
