Projects and monitors (moni tor) can meet the energy saving regulations of EPA, VESA, NUTEK, and the minimum specifications also need to be less than 5 watts (w). There is no E2000 ^, TC099 regulations, and its minimum power saving The demand for wattage is less than 3 watts. 'Right now, it is controlled by the current circuit design, which requires more expensive design costs to meet the requirements of Ε200 00 and TC〇99. Figure 1 is a conventional energy-saving power-saving control block, which mainly includes a transformer Tr, a wave wide modulator pm, an auxiliary power supply Αυχ · power, an electronic switch sw, and a microcontroller MCU.

Power來供其基本之運作，因此仍會 有電力的消耗。除此之外，由於只是切斷電子開關s w輸出 的電源Vo，所以只能使監視器内部其它電路不消耗電力， 卻無法使電源供應器内部的各元件處於省電的狀態。對電 源供應器而只是負載（loading)下降而已，而事實上，變 壓器Tr及波寬調變器（PWM)等元件仍會不時地通以電流， 持續地消耗電力。 若維持習用的作法，則為迎合上述省電模式下需耗電 小於3瓦的要求，顯然必需花費較昂貴的設計成本在改善 電源供應器内部各元件上。而現今低價電腦的盛行，設計 低成本的電腦為勢之所趨，習用的作法，顯然已見汰勢， 難以符合潮流。 本案的目的即因應潮流之所趨而發展出一套低成本的 能源省控制技術，來符合E2 000和TC099的規章，當然也符 合其它有關能源省電規章。 為達上述目的’本案提出一種具省電控制之電源模 組’因應一信號以進入一省電模式，其包含：一電源模 組’具一用以控制該電源模組得以穩定輸出之—電源之— 調變器；以及一控制電路，係連接至該電源模組，且因應 該信號以控制該電源模組之該調變器，使該調變器控制該 電源模組進入該省電模式者。 其中，該信號係為一螢幕之水平信號或垂直信號。該 電源模組更包含：一變壓器，係連接至該調變器，並藉^416030 r * — ---- " V.

Power must be provided for its basic operation, so it is still There will be power consumption. In addition, since the power supply Vo output from the electronic switch sw is only cut off, the other circuits inside the monitor can only consume no power, but the components inside the power supply cannot be kept in a power-saving state. For the power supply, only the loading is reduced. In fact, components such as the transformer Tr and the wave width modulator (PWM) still pass current from time to time to continuously consume power. If the conventional practice is maintained, in order to meet the requirement of power consumption less than 3 watts under the above power saving mode, it is obviously necessary to spend more expensive design costs on improving the internal components of the power supply. Nowadays, with the prevalence of low-cost computers, the design of low-cost computers is inevitable. It is clear that customary practices have eliminated the trend and are difficult to meet the trend. The purpose of this case is to develop a set of low-cost energy-saving control technologies in accordance with the trend of the trend, in order to comply with the regulations of E2 000 and TC099, and of course to comply with other energy-saving regulations.

The difference is that in this case, Wuli provides additional auxiliary power Aux Power to the microcontroller. In the power saving mode, the control circuit directly wakes up the power by detecting the horizontal signal or vertical signal of the glory. Provider. So the cost of auxiliary power can be reduced. In addition, in the power saving mode, the control circuit directly controls the wave width modulator, so that the voltage is no longer output, that is, the wave width modulator and the transformer are maintained in an inoperative state at this time, so it can save More power, which in turn meets the latest energy regulations E20 00 and TC099 not exceeding 3w. Of course, the most important thing is that the control circuit can be achieved with a lower-cost circuit, which greatly reduces the cost of the entire power module. The method and principle of the control circuit are detailed as follows: Figure 3 is a preferred embodiment of the present invention. Among them, the transformer Tr is controlled by the wave width modulator to stably output voltages of 80 volts, 15 volts, and 6.3 volts.

2不會有充電電壓，所以穩壓二極體ZD1〇1和電晶體“〇2 就不會被turn on，波寬調變器就能正常開機啟動。 圖六為另一種省電延遲控制電路。另一種的波寬調變 器積體電路將場效電晶體q1〇1結合在一起，所以在接線上 就不必額外再接一個場效電晶體，而是直接輸出到變壓器 Τι：即可。另外，接腳4是穩壓迴授的輪入端，而光耦合積 體電路IC102是一顆穩壓迴授積體電路。 圖七又為色一種省電延遲控制電路。相同的電路控制 也可使用在編號為UC3842或不同廉牌之相同規格的波寬調 變器積體電路上’其中腳接1及接腳2係與省電延遲控制線 路相連接。 圖八為指示燈控制電路。當正常工作時，回授電壓 + F β從監視器水平線路利用麵合方式感應到一個脈衝，經 二極體D1 04及電容C1 03整流成一直流準位Vc。當直流準位 Vc建立後，電晶體qi 〇3導通，電壓Vb為低電壓。當電壓vb 為低電位時，定電流電路被關閉，無電流流過，所以發光 二極體的橙燈不亮，而二極體D103此時開啟，發光二極體 的綠色燈被點亮。其中手動開關SW1 01係為監視器的電源 開關’ 2 A、2 B為中心點，可切換到1 A、1B或3 A、3 B。 當進入省電模式時，回授信號+ FB無訊號，則電壓Vc 為低電位，電晶體Q1 03關閉’定電流電路正常工作，提供 電流流過橙色發光二極體，使其顯示橙色燈。 由上述之圖解及說明可知，本案係以低成本的設計方 式’達到電源供應器的省電功能’其係藉由控制波寬調變2 will not have a charging voltage, so the voltage regulator diode ZD1〇1 and the transistor "〇2 will not be turned on, and the wave width modulator can be turned on and started normally. Figure 6 shows another power-saving delay control circuit. The other integrated circuit of the wave width modulator integrates the field effect transistor q1〇1, so there is no need to connect an additional field effect transistor on the wiring, but it is directly output to the transformer Ti :. In addition, pin 4 is the round-in terminal of stabilized feedback, and the optical coupling integrated circuit IC102 is a stabilized feedback integrated circuit. Figure 7 is a power-saving delay control circuit. The same circuit control also Can be used on UC3842 or different inexpensive brand of the same specifications of the wave width modulator integrated circuit 'where pin 1 and pin 2 are connected to the power-saving delay control circuit. Figure 8 shows the indicator control circuit. During normal operation, the feedback voltage + F β is induced from the horizontal line of the monitor by a face-to-face method, and a pulse is rectified by the diode D1 04 and the capacitor C1 03 into the DC level Vc. After the DC level Vc is established, The transistor qi 〇3 is turned on, and the voltage Vb is a low voltage. When the voltage vb is low, the constant current circuit is turned off and no current flows, so the orange light of the light-emitting diode is off, and the diode D103 is turned on at this time, and the green light of the light-emitting diode is turned on. The manual switch SW1 01 is the monitor's power switch '2 A, 2 B is the center point, and can be switched to 1 A, 1B or 3 A, 3 B. When entering the power saving mode, the feedback signal + FB no signal When the voltage Vc is low, the transistor Q1 03 is turned off, and the constant current circuit works normally, and the current is provided through the orange light-emitting diode to make it display an orange light. From the above illustration and description, it can be known that this case is a low-cost The design method 'achieves the power saving function of the power supply' is controlled by controlling the width of the wave

Description of the invention (9) The input and output terminals of the error amplifying (err0r amp) of the (PWM) integrated circuit enable the wave width modulation integrated circuit to be turned on (turn 〇n) or turned off (turn 〇ff), Instead of using an auxiliary power supply (Aux. Power) to provide power to the micro controller, it is necessary to control the state of the wave width modulation integrated circuit, which has a higher design cost. This case may be done by anyone who is familiar with the art, but it is not inferior to those who want to protect the scope of patent application.彳 彳 > Decoration
