AUTOMATIC DC POWER SUPPY TO COMPUTER SYSTEM WHEN THE POWER IS OFF WITHOUT USING UPS

Abstract

A power supply unit (PSU) converts mains AC to low-voltageregulated DC power for the internal components of a computer.Modern personal computers universally use a switched-modepower supply. Some power supplies have a manual selector forinput voltage, while others automatically adapt to the supplyvoltage. Most modern desktop personal computer power suppliesconform to the ATX form factor. ATX power supplies are turnedon and off by a signal from the motherboard. They also provide asignal to the motherboard to indicate when the DC power lines arecorrect so that the computer is able to boot up. While an ATXpower supply is connected to the mains supply it provides a 5 Vstand-by (5VSB) line so that the standby functions on the computerand certain peripherals are powered. The most recent ATX PSUstandard is version 2.31 of mid-2008. The computer system willget power from UPS. The UPS supplies electricity to run oursystem. If the power is off, then the UPS will run only certainperiod of time. Then the system will automatically shut down. Toavoid this problem, we propose one electro magnet motor to savecurrent when the system is runs and utilize the current when thepower is off. Generally we are using two types of motors to givecurrent to the component. One is Magnet electro and another one iselectro magnet. Electro magnet motor inside having electric fields.If the fields are runs means it will generate electricity. This typesof motors are mostly used in Turbine control and other system whowants battery powered power supply unit. This technique utilizesthe new component reactor to save electricity. Monitor and CPUattached to this reactor. When power is off, then the reactor willautomatically run and it supply current to both UPS and Monitor.Without power supply we will run our system effectively.
