Abstract
Disclosed is an electronic switch circuit including a switching thyristor with two switch terminals that are connected to a controlled circuit. A trigger circuit is coupled to the gate terminal of the thyristor to selectively supply trigger signals and the trigger circuit receives its power from a power supply which is connected to switch terminals and draws its energy from the controlled circuit. An energy storage capacitor in the power supply provides trigger energy when the voltage across the switch terminals is approximately zero, such as at A.C. crossovers. The thyristor exhibits zero voltage switching.
