Micro-electromechanical system based soft switching

A system (10) is presented. The system (10) includes detection circuitry (14) configured to detect occurrence of a zero crossing of an alternating source voltage (36) or an alternating load current (42). The system also includes switching circuitry (12) coupled to the detection circuitry (14) and co...

Summary:A system (10) is presented. The system (10) includes detection circuitry (14) configured to detect occurrence of a zero crossing of an alternating source voltage (36) or an alternating load current (42). The system also includes switching circuitry (12) coupled to the detection circuitry (14) and comprising a micro-electromechanical system switch (20). Additionally, the system (10) includes control circuitry (16) coupled to the detection circuitry (14) and the switching circuitry (12) and configured to perform arc-less switching of the micro-electromechanical system switch (20) responsive to a detected zero crossing of an alternating source voltage (36) or alternating load current (42).
