<p>Provided is an AC voltage control device for adjusting the voltage of a load to be connected with an AC power source, by a convenient method. In this AC voltage control device, a magnetic energy regeneration switch having a condenser and an AC switch circuit connected in parallel is connected between the AC power source and the load. The AC switch circuit is turned ON several mS from such a timing of a zero condenser voltage as occurs twice for one current cycle, so that a condenser current is bypassed to reduce a reactance voltage thereby to adjust a load voltage.</p> |
