Abstract
Abstract A voltage regulator for a magneto AC generator comprising a battery charging generator coil and a loading generator coil, said voltage regulator comprising a first voltage divider to detect a voltage proportional to a terminal voltage of a battery; a second voltage divider to detect a voltage proportional to an output voltage of the loading generator coil; and a controlled rectifier arranged to short-circuit the battery charging generator coil and adapted to be conductive when either of the voltages detected by the first and second voltage dividers is greater than a predetermined value, the battery charging and loading generator coils being arranged to be magnetically bonded with each other.
