Abstract
The present invention relates to an energy-saving power converter having a suspend mode. The power converter includes an output port for being electrically connected to the electricity consuming device; a voltage-transforming unit for outputting an output voltage appropriate to the needs of the electricity consuming device; a sensor for assessing the electricity consuming mode of the electricity consuming device, and a switch for selectively determining whether the sensor is to be powered. A wake-up unit is further provided to generate a wake-up signal for activating the voltage-transforming unit to provide power normally. The invention therefore solves the problem of unnecessary energy consumption resulted from a constant voltage conversion during the course when the electricity consuming device need not be supplied with power.
