Abstract
The utility model relates to an intelligent power supply special for computer. After the prior computers are used, the power switch must be turned off but the computer host, the printer, the monitor, and the sound power supply are still under the stand-by state, thereby affecting the safety and the service life of the computers. The utility model aims at developing a special power supply which can be arranged in the prior computer host switch power supplies. When a switch AN is pressed, a computer host switch power supply is connected, an auxiliary power supply (V2) in the switch power supply supplies power to a circuit by a diode D3, a capacitor C1 is charged and then charges a capacitor C2 by a D1; meanwhile, a R2 supplies bias current to a triode Q1Q2, the triode Q1Q2 starts to work and then a relay J starts to work. When a computer stops working and is turned off, the voltage of a current transformer CT produced by a diode D2 is lower than the voltage of the C2, discharge is started, the bias current cannot be supplied to the triode Q1Q2 after a certain period of time, and the relay J stops working. Therefore, the computer host, the printer, the monitor and the sound power supply are automatically turned off.
