Abstract
A control for supplying not more than one complete cycle of an alternating current upon command. The circuit has a plurality of gate controlled switching devices and a command switch. An energy storage device has one of the switching devices connected in the circuit for conducting a short time after the beginning of each current excursion of a specific polarity, and another of the switching devices is connected in series between a power source and a load for supplying energy to the load when gated. A third switching device is adapted to conduct, when gated, for depleting energy from the storage device only when the command switch so indicates. Conduction of the third switching device gates the other switching device and occurs only during current excursions of the desired polarity when the one switching device is non-conducting.
