ABSTRACT:
A micro-power stand-by system is provided which minimizes power supplied to and the utilization of a stand-by power supply circuit and the resultant production of electro-magnetic interference (EMI) during normal electronic device operation. In one embodiment, the stand-by power supply circuit includes at least one capacitor in electrical communication with at least one stand-by relay, with the capacitor electrically connected to an AC line. The capacitor powers the stand-by power supply circuit and the stand-by relay. At least one switch is located a prearranged distance from a main power supply circuit, and is electrically connected to the AC line and the stand-by relay to provide normal operation for the main power supply circuit. In another embodiment, the switch includes a stand-by switch and a main power switch which provide an inrush current limiting resistor during initial power-on for safety reasons and a bypass of the inrush current limiting resistor during normal operation, respectively.
