Abstract
A system for protecting a MEMS relay switch system that controls electric current to a load includes a parallel resonant circuit in series with the MEMS relay switch system. The parallel resonant circuit includes an auxiliary switch in series with a capacitor configured to be pre-charged by a voltage source, and an inductor in parallel with the auxiliary switch and the capacitor. The inductor is in series with the MEMS relay switch system. A method includes receiving a signal, activating an auxiliary switch, determining if the received signal is a turn OFF or a turn ON signal, and depending on the received signal, setting a time delay within a resonant half cycle of a parallel resonant pulse circuit, turning off the auxiliary switch, and pre-charging a capacitor of the parallel resonant pulse circuit.
