ABSTRACT:
An alternating current power source apparatus comprises an AC generator having a field coil which is driven by an engine; a first rectifier having one or more thyristors which rectify the AC output of the AC generator; a second rectifier having one or more thyristors which is connected in parallel to said first rectifier to give the output having a polarity reverse to the polarity of the output of said first rectifier; an AC driving load connected to said first and second rectifiers; a voltage control device for controlling the output voltage of said generator to a predetermined value by controlling a field current passing through said field coil; an oscillator for oscillating at a desired frequency; and a gate signal generating circuit which is controlled by the output of said oscillator so as to feed a turn-on signal alternately to said gate circuit of said first rectifier and said gate circuit of said second rectifier.
