本發明之流程如下：The process of the present invention is as follows:
當該電子裝置20自該具有低待機功耗之電源供應裝置10移除時，該無載偵測單元108係藉由偵測該二次側變壓器線圈114的脈寬調變的波形變化（頻率及工作週期）得知；接著，該無載偵測單元108關閉該輸出開關單元102，且該無載偵測單元108係藉由一第二光耦合器發射部10802及一第二光耦合器接收部10822（如第二圖所示）關閉該功因校正與脈寬調變控制器112（即該具有低待機功耗之電源供應裝置10休眠，藉以節能）。When the electronic device 20 is removed from the power supply device 10 having low standby power consumption, the unloaded detecting unit 108 detects a waveform change of the pulse width modulation of the secondary side transformer coil 114 (frequency And the duty cycle detection unit 108, wherein the unloaded detection unit 108 turns off the output switch unit 102, and the unloaded detection unit 108 is coupled to a second optical coupler transmitting portion 10802 and a second optical coupler. The receiving unit 10822 (shown in the second figure) turns off the power factor correction and the pulse width modulation controller 112 (i.e., the power supply device 10 having low standby power consumption sleeps, thereby saving energy).
當該具有低待機功耗之電源供應裝置10休眠時，該有載偵測單元104即偵測該電子裝置20是否重新連接該具有低待機功耗之電源供應裝置10；當該電子裝置20重新連接該具有低待機功耗之電源供應裝置10時，該有載偵測單元104即驅動該間歇驅動單元106，該間歇驅動單元106驅動該啟動單元110，該啟動單元110驅動該功因校正與脈寬調變控制器112（即啟動該具有低待機功耗之電源供應裝置10）。When the power supply device 10 with low standby power consumption sleeps, the load detection unit 104 detects whether the electronic device 20 reconnects the power supply device 10 with low standby power consumption; when the electronic device 20 is re-established When the power supply device 10 having low standby power consumption is connected, the load detecting unit 104 drives the intermittent driving unit 106, and the intermittent driving unit 106 drives the starting unit 110, and the starting unit 110 drives the power factor correction and The pulse width modulation controller 112 (i.e., activates the power supply device 10 having low standby power consumption).
此時，該無載偵測單元108偵測到該電子裝置20連接至該具有低待機功耗之電源供應裝置10，因此該無載偵測單元108不會關閉該輸出開關單元102及該功因校正與脈寬調變控制器112。At this time, the no-load detecting unit 108 detects that the electronic device 20 is connected to the power supply device 10 having low standby power consumption, so the unloaded detecting unit 108 does not turn off the output switching unit 102 and the work. The controller 112 is modulated by the pulse width modulation.
其中，當該具有低待機功耗之電源供應裝置10休眠時，係藉由一放電電容10602（如第四圖所示）放電以提供電源予該有載偵測單元104及該間歇驅動單元106等相關部件（也因此該有載偵測單元104及該間歇驅動單元106等相關部件的元件的功耗必須極小）。When the power supply device 10 with low standby power consumption is dormant, it is discharged by a discharge capacitor 10602 (shown in FIG. 4) to provide power to the on-load detection unit 104 and the intermittent drive unit 106. The power consumption of the components of the related components (and therefore the components of the associated components such as the load detection unit 104 and the intermittent drive unit 106 must be extremely small).
而該放電電容10602的儲電會被耗盡；因此，在該具有低待機功耗之電源供應裝置10休眠時，該間歇驅動單元106係每隔一預定時間（例如為三百秒）驅動該啟動單元110，該啟動單元110驅動該功因校正與脈寬調變控制器112（即喚醒該具有低待機功耗之電源供應裝置10），藉以對該放電電容10602進行充電。The storage of the discharge capacitor 10602 is exhausted; therefore, when the power supply device 10 having low standby power consumption is dormant, the intermittent drive unit 106 drives the device every predetermined time (for example, three hundred seconds). The startup unit 110 drives the power factor correction and pulse width modulation controller 112 (ie, wakes up the power supply device 10 having low standby power consumption) to charge the discharge capacitor 10602.
再者，當該具有低待機功耗之電源供應裝置10被喚醒以對該放電電容10602進行充電時，若該無載偵測單元108偵測該電子裝置20仍然沒有重新連接至該具有低待機功耗之電源供應裝置10，則如同上述，接著該無載偵測單元108即關閉該輸出開關單元102及該功因校正與脈寬調變控制器112，且該具有低待機功耗之電源供應裝置10每隔該預定時間被喚醒。Moreover, when the power supply device 10 having low standby power consumption is awakened to charge the discharge capacitor 10602, if the unloaded detection unit 108 detects that the electronic device 20 is still not reconnected to the low standby The power supply device 10 of the power consumption is as described above, and then the no-load detection unit 108 turns off the output switch unit 102 and the power factor correction and pulse width modulation controller 112, and the power supply with low standby power consumption The supply device 10 is woken up every predetermined time.
其中，該功因校正與脈寬調變控制器112即為該具有低待機功耗之電源供應裝置10的核心，係用以控制該主轉換器116等相關部件以將交流電源轉換成直流電源。The power factor correction and pulse width modulation controller 112 is the core of the power supply device 10 with low standby power consumption, and is used to control the main converter 116 and other related components to convert the AC power into a DC power source. .

The third transistor 10208 is electrically connected to the fifteenth resistor 10206, the sixteenth resistor 10210, and the seventeenth resistor 10212.
當該輸出開關單元102被關閉時，該輸出開關單元102係用以使該具有低待機功耗之電源供應裝置10的輸出端與該電子裝置20隔離，所以該有載偵測單元104能單純地偵測該電子裝置20是否重新連接至該具有低待機功耗之電源供應裝置10。When the output switch unit 102 is turned off, the output switch unit 102 is configured to isolate the output end of the power supply device 10 having low standby power consumption from the electronic device 20, so the load detection unit 104 can be simply It is detected whether the electronic device 20 is reconnected to the power supply device 10 having low standby power consumption.
請參考第四圖，其係為本發明之間歇驅動單元方塊圖。該間歇驅動單元106包含該放電電容10602、一第一運算放大器10604、一第一光耦合器發射部10606、一第一電阻10608、一第一電容10610、一第二電阻10612、一第三電阻10614、一第二電容10616、一第一二極體10618、一第四電阻10620、一參考電壓源10622及一第二二極體10624。 該第一運算放大器10604包含一第一運算放大器輸出端10626、一第一運算放大器第一輸入端10628及一第一運算放大器第二輸入端10630。Please refer to the fourth figure, which is a block diagram of the intermittent driving unit of the present invention. The intermittent driving unit 106 includes the discharge capacitor 10602, a first operational amplifier 10604, a first optical coupler transmitting portion 10606, a first resistor 10608, a first capacitor 10610, a second resistor 10612, and a third resistor. 10614, a second capacitor 10616, a first diode 10618, a fourth resistor 10620, a reference voltage source 10622 and a second diode 10624.

該第一運算放大器輸出端10626電性連接至該第一電阻10608、該有載偵測單元104及該第一電容10610；該第一運算放大器第一輸入端10628電性連接至該第二電阻10612及該第三電阻10614；該第一運算放大器第二輸入端10630 電性連接至該第二電容10616及該第一二極體10618。The first operational amplifier output 10626 is electrically connected to the first resistor 10608, the loaded detection unit 104 and the first capacitor 10610; the first operational amplifier first input terminal 10628 is electrically connected to the second resistor The first input terminal 10630 of the first operational amplifier is electrically connected to the second capacitor 10616 and the first diode 10618.
該放電電容10602電性連接至該第二二極體10624、該第一運算放大器10604、該第一光耦合器發射部10606、該第二電阻10612及該有載偵測單元104；該參考電壓源10622電性連接至該第一二極體10618及該第四電阻10620；該第一電阻10608電性連接至該第一光耦合器發射部10606。The discharge capacitor 10602 is electrically connected to the second diode 10624, the first operational amplifier 10604, the first optical coupler transmitting portion 10606, the second resistor 10612, and the loaded detecting unit 104; the reference voltage The source 10622 is electrically connected to the first diode 10618 and the fourth resistor 10620; the first resistor 10608 is electrically connected to the first optocoupler emitting portion 10606.
該具有低待機功耗之電源供應裝置10更包含一二次側電壓提供單元10632，該二次側電壓提供單元10632係用以在該具有低待機功耗之電源供應裝置10處於工作狀態下提供電源予該具有低待機功耗之電源供應裝置10之元件；該第二二極體10624電性連接至該第四電阻10620、該輸出開關單元102、該無載偵測單元108及該二次側電壓提供單元10632。The power supply device 10 having low standby power consumption further includes a secondary side voltage supply unit 10632 for providing the power supply device 10 with low standby power consumption in an active state.

該第二電阻10612及該第三電阻10614所構成之迴路之電壓下降斜率大於由該第二電容10616、該第一二極體10618、該參考電壓源10622及該第四電阻10620所構成之定電壓參考點之電壓下降斜率；所以當該第一運算放大器第一輸入端10628的電壓低於該第一運算放大器第二輸入端10630的電壓時，該第一運算放大器10604的輸出邏輯即產生改變。The voltage drop slope of the loop formed by the second resistor 10612 and the third resistor 10614 is greater than the second capacitor 10616, the first diode 10618, the reference voltage source 10622, and the fourth resistor 10620. The voltage of the voltage reference point drops the slope; therefore, when the voltage of the first input terminal 10628 of the first operational amplifier is lower than the voltage of the second input terminal 10630 of the first operational amplifier, the output logic of the first operational amplifier 10604 changes. .
當該第一運算放大器輸出端10626的邏輯狀態為1時，該第一光耦合器發射部10606不傳送光信號至一第一光耦合器接收部11016（如第五圖所示），所以該功因校正與脈寬調變控制器112為關閉。When the logic state of the first operational amplifier output terminal 10626 is 1, the first optical coupler transmitting portion 10606 does not transmit an optical signal to a first optical coupler receiving portion 11016 (as shown in FIG. 5), so The power factor correction and pulse width modulation controller 112 is off.
當該第一運算放大器輸出端10626的邏輯狀態為0時，該第一光耦合器發射部10606傳送光信號至該第一光耦合器接收部11016，所以該功因校正與脈寬調變控制器112為啟動。When the logic state of the first operational amplifier output terminal 10626 is 0, the first optical coupler transmitting portion 10606 transmits an optical signal to the first optical coupler receiving portion 11016, so the power factor correction and the pulse width modulation control The device 112 is activated.

When the power supply device 10 having low standby power consumption is in a sleep state, the first optocoupler transmitting portion 10606 does not have a current flowing, and the logic state of the first operational amplifier output terminal 10626 is 1. Such an inverse logic design allows the weak electrical energy of the discharge capacitor 10602 to support the predetermined time for up to three hundred seconds.
