Embodiment Construction

[0029] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] The core idea of ​​the present invention is to control the on / off of the alternating current (AC) input of the computer power supply by monitoring the on / off signal on the computer mainframe through the monitoring control device.

[0031] refer to figure 2 , the zero-standby computer power supply of the first embodiment is proposed. The computer power supply includes a main power supply 10 and a monitoring control device 20 . The main power supply 10 includes a main circuit 11 and a standby circuit 12 . After the main power supply 10 is started, the main circuit 11 outputs various DC power supplies, such as ±12V, +5V, +3.3V. The standby circuit 12 outputs a +5Vsb standby power supply to provide a working voltage for starting the mainboard 3 .

[0032] The monitoring control device 20 includes a standby mon...

Abstract

The invention relates to a zero-standby computer power supply, comprising a main power supply and a monitoring control device. The monitoring control device is connected with a switch key of a computer host and comprises a standby monitoring unit, a switch execution unit and a micro power supply unit. The standby monitoring unit is used for monitoring the state of the switch key and generating a triggering signal. The switch execution unit is connected between the output end of an alternating current power supply and the input end of the main power supply, is used for respectively receiving the triggering signal of the standby monitoring unit and the control signal of the main power supply, and controlling the switch on / off of the power supply input of the main power supply. The micro power supply unit respectively supplies driving power for the standby monitoring unit and the switch execution unit. In the invention, the standby monitoring unit monitors the switch signal of the switch key and generates the triggering signal to control the switch execution unit to be on / off, therefore, by means of the zero-standby computer power supply, under the condition of standby (i.e. the computer is shut down), the power input of the computer main power supply is switched off so that the zero-standby power consumption is realized.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a zero-standby computer power supply. Background technique [0002] refer to figure 1 , the existing computer power supply includes a main circuit and a standby circuit. The PS-ON end on the power supply is connected to the motherboard. The ON / OFF terminal on the main board is connected with the switch key PWS on the host computer, and is used for monitoring the state of the switch key PWS. When the computer is started, the ON / OFF terminal of the main board receives the power-on signal of the switch key PWS, pulls down the voltage of the PS-ON terminal on the power supply, the main circuit starts, and the output terminals of the ±12V, +5V, +3.3V power supply generate corresponding The output voltage for the computer to start. The main circuit can only be started after the AC power input is connected and the PS-ON signal is received, and the output DC power is generated...
