Abstract: A stand-by power supply circuit is provided that controls power consumption and decreases electromagnetic interference during operation of a television. In one embodiment, the stand-by power supply circuit is connected to a switch that is connected to an AC line. The switch is located a prearranged distance from a main power supply circuit and provides a method for reducing the electromagnetic interference caused by the stand-by power supply circuit in an operating television by disconnecting the AC line from the stand-by power supply circuit and connecting the AC line to the main power supply circuit via the switch during a power-on mode/operation.

Abstract: A combination includes (1) a host device having a high voltage generator, where the host device is configured to perform a function other than dust collection or electrostatic precipitation; and (2) an electrostatic precipitator configured to share the output of the high voltage generator of the host device. A method of providing an electrostatic precipitator includes integrating an electrostatic precipitator into a host device that includes a high voltage generator, where said host device is configured to perform a function other than electrostatic precipitation; and sharing an output of the high voltage generator between the electrostatic precipitator and the host device. In some examples, the host device is a television set.

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.
