ABSTRACT:
A zero voltage switching circuit for controlling current to a serially arranged load and AC voltage source including first and second photosensitive silicon controlled rectifiers having a gate, anode, and cathode terminals, the anode-cathode terminals being arranged to be connected in inverse parallel across the load and AC voltage source, apparatus for applying input signals to generate light to enable the first and second photosensitive silicon controlled rectifiers, apparatus for providing a voltage range within which the photosensitive silicon controlled rectifiers operate, apparatus for clamping the gate terminals of each of the photosensitive silicon controlled rectifiers to its cathode in the absence of input light signals to the photosensitive silicon controlled rectifiers, and apparatus for opening the circuit between the gate and rectifier of each photosensitive silicon controlled rectifier in the presence of input light signals.
