Embodiment Construction

[0010] As shown in Figure 1, the present invention is improved on the basis of the original common computer power supply. Ordinary computer power supply mainly includes the following contents: including EMI filter circuit, rectification filter circuit, DC / DC conversion, output rectification filter circuit, DC power output, and the output of DC power supply for computer hardware Power supply, in the above-mentioned circuit, also includes switch machine control part and PWM control part, 5vSB standby circuit, the above-mentioned part is commonly used in the computer power supply that is used now. In the present invention, the following improvements are mainly carried out. The described circuit is also provided with a low-power circuit successively, and the transistors adopted in the original 5vSB standby circuit are replaced by low-power IC chips, so that the above-mentioned 5vSB standby circuit The power consumption in the computer is greatly reduced. The energy-saving effect o...

Abstract

The invention belongs to the computer domain, and basically relates to an energy-saving power used in computers; especially it is a new pattern power with distinct energy-saving effect when the computer and display is in sleeping mode. The two primary improvements of the invention replace the original transistors with IC chips, great decreasing the integral energy consumption of the computer's power, and obtaining distinct energy-saving effect. Setting automatic output / cut-out devices and automatic output / cut-out circuits, combining the power of the display into the power of the computer, with the function of the former devices and circuits, makes the integration of the open / close operations of the display and the open / close operations of the computer, in order to avoid the unnecessary power consumption of forgetting to close the display. The invention provides a low energy consumption power that can decrease the energy consumption to about 1W when the computer is in sleeping mode.

Description

【Technical field】 [0001] The invention belongs to the field of computers, and mainly relates to an energy-saving power supply used in computers, especially a new type of power supply with remarkable energy-saving effect when the computer and the display are in a standby state. 【Background technique】 [0002] Now computers have become commonly used office equipment at work, and in the field of family life, they have also developed into indispensable household equipment. The use and possession of computers are increasing day by day. At the same time, due to the continuous improvement of hardware equipment and the increase of other auxiliary equipment, the energy consumption of current computers is getting higher and higher. Especially in some large and medium-sized cities, the proportion of the power consumption of computers in daily life is constantly increasing. Now that energy is becoming more and more tense, the energy consumption of computers has attracted the attention ...
