Abstract
A method for operating an alternating-current (AC) controller system includes providing a first bi-directional switch coupled to a load and an AC power source. The first bi-directional switch is a solid-state device. The first switch is turned on in a first half-cycle of an AC cycle. The first switch is turned off in the first half-cycle of the AC cycle.
