電源供應裝置2之降低魏耗損的策略是:於待機 =莫式下,關閉輸出電路13,利用開關電路21的導通或: ^通’控制外部電源訊號之傳導,例如:姻開關電路: =外部電源訊號之第-週期或是第二週期直接傳遞至》 機電路u,以避免整流電路η、放電電路22、功因校正, $ 12之電能耗損。因此’僅外部麵訊號之部分週期 &供部分的電祕號至待機電路14,並謂免整流電; =、放電電路22、功因校正電路12之電能耗損,藉此降/ 整體電源供織置2之整體電能耗損。於本實施例,第. 週期為外部電源訊號之正半週期,而第二週期為外部電> 8/19 201124835 訊號之負半週期,且外部電源訊號為—交流訊號。 ”並且’由於電源供應裝置2具有一放電電路22,放電 電路22可於外部電源10移除時,受控於控制電路23而導 通’使得電源供應裝置2之電容負載所 儲存之電荷得以透 過,電電路22之放電路徑進行快速的放電,藉此,當移除 電源1G之後’電源供應裝置2之内部電容負載之儲電 里即=快速降低,以避免漏電,並能更精確控制㉟放時間。The strategy for reducing the Wei loss of the power supply device 2 is: in the standby mode, the output circuit 13 is turned off, and the conduction of the switch circuit 21 is used or: ^T' is used to control the conduction of the external power signal, for example: the switch circuit: = external The first period or the second period of the power signal is directly transmitted to the "machine circuit u" to avoid the power consumption loss of the rectifier circuit η, the discharge circuit 22, the power factor correction, and $12. Therefore, only part of the period of the external surface signal & part of the electric secret number to the standby circuit 14, and said that the rectifier power; =, the discharge circuit 22, the power factor correction circuit 12 electrical energy loss, thereby reducing / overall power supply The overall electrical energy consumption of the weave 2. In this embodiment, the first cycle is the positive half cycle of the external power signal, and the second cycle is the negative half cycle of the external power > 8/19 201124835 signal, and the external power signal is an ac signal. "And since the power supply device 2 has a discharge circuit 22, the discharge circuit 22 can be controlled by the control circuit 23 when the external power source 10 is removed, so that the charge stored by the capacitive load of the power supply device 2 is transmitted, The discharge path of the electric circuit 22 is rapidly discharged, whereby after the power supply 1G is removed, the internal capacitive load of the power supply device 2 is rapidly reduced to avoid leakage, and the 35 time can be more accurately controlled. .
