Abstract
A system is presented. The system includes detection circuitry configured to detect occurrence of a zero crossing of an alternating source voltage or an alternating load current. The system also includes switching circuitry coupled to the detection circuitry and comprising a micro-electromechanical system switch. Additionally, the system includes control circuitry coupled to the detection circuitry and the switching circuitry and configured to perform arc-less switching of the micro-electromechanical system switch responsive to a detected zero crossing of an alternating source voltage or alternating load current.
