Abstract
A bi-directional solid state switch has two main transistors which are connected to each other with input to input and input referenced output to input referenced output. Each unreferenced transistor output is separately connected to an output terminal of the switch. An electrical impedance is connected between the input connection and the input referenced output connection. A driver signal is connected across the input connection and one output terminal. This circuit topology is counter-intuitive, but provides advantages which can include eliminating the need for electrical isolation, being capable of turning on or off at any time, at or between zero crossings, having a high speed of response, simplicity, reliability, cost-effectiveness, and energy-efficiency.
