Abstract
A rectifying system for a magnet-type AC generator comprises a rectifier circuit including a composite bridge of a plurality of diodes and a plurality of thyristors for regulating and rectifying the output voltage of the AC generator, a first phase control circuit for applying a firing signal to the thyristors, a neutral-point diode, a neutral-point thyristor, and a second phase control circuit for controlling the phase of the neutral-point thyristor. The neutral-point thyristor is phase-controlled, and the voltage applied to a battery with an electrode thereof connected to the diodes is thereby regulated.
