本論文對有長時間待機功耗問題的家電提出了一個降低待機功耗的設計。待機狀態是指家電連接著市電，但是在不使用或是關閉電源的時候。某些家電在待機狀態時仍有著1到3 W的待機功耗，為降低此待機功耗，在本論文中提出一個設計，以超電容(Ultracapacitor, UC)，閂鎖繼電器(Latching relay)，微控制器(μC)建構低待機功耗電路，以此設計實作的低待機功耗家電有：低待機功耗插座、低待機功耗紅外線人體感應照明燈、低待機功耗微波爐、低待機功耗自動沖水裝置。實驗結果顯示此設計可以降低待機功耗達到95 %以上，並且不影響家電的原有功能。

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.
