| Summary: | 博士 === 國立臺灣科技大學 === 電子工程系 === 102 === In this dissertation, the design issues for reducing the power consumption in the standby state of home appliances, which has long been an unsolved problem, are considered. Here, the standby state means that the power button of an appliance is turned off or an appliance does not execute its main function while the appliance is being plugged into an ac socket. In the standby state, an appliance usually consumes 1 to 3 W. To remove such power consumption in the standby state, a design paradigm, consisting of an ultra-capacitor (UC), latching relays, and a microcontroller (μC), is proposed in this dissertation and implemented in the following appliances: a low standby power socket, a zero standby power PIR luminaire, an ultra-low standby power microwave oven, and an ultra-low standby power auto flushing device. Experimental results show that the standby power can be reduced more than 95% while the performance of the appliances is kept unchanged.
