ABSTRACT:
An arrangement for controlling power during any given half cycle of AC power is disclosed herein and includes a gated switching device connected across an AC voltage supply, and a charging capacitor also connected with the supply voltage and adapted to discharge into the gate of the switching device for firing the latter under predetermined, externally controlled conditions. A low voltage control circuit is also disclosed herein and is especially suitable for use with the switch arrangement just recited, specifically for causing the capacitor to discharge at a particular point during a particular half cycle in the AC voltage supply.
