Method and implementation for reducing stand by power consumption in SMPS with low-speedy power line communication

This paper is designated to introduce the method of reducing stand-by Power of SMPS applied PLC(Power Line Communication) and its implementation. PLC modem consists mainly of PLC Module, Coupling Circuit, ZCP(Zero-Cross Point) Circuit and Power Supply Circuit. By controlling power from Power Supply Circuit to PLC Module and ZCP Circuit, the reduction of Stand-by Power is established. When this method is applied to SMPS used for a low-speed PLC, about 50% power reduction is provided, compared to the other case to which it is not applied.
