ABSTRACT:
A control circuit provides full range power control to a pair of electrical loads via a single two-wire power cable by controlled switching of a bidirectional solid state switch during each consecutive half-wave cycle to supply power to one load during each positive half-wave cycle and to the other load during each negative half-wave cycle. The switching during each half-wave cycle is controlled by a respective trigger circuit. Interference by power supplied to one load with the operation of the other load is prevented by removing any residual voltage from the respective trigger circuit at the end of each half-wave cycle.
