View Pc Power Supply Circuit Diagram Gif. Powefull pc power supply working with two voltage rails. On this page i collect the schematics of switching supplies for computers (smps) atx v 1.0, atx v 2.0 and some at, which i found on internet.
Power supplies and control schematics.
The switching power supply has replaced the transistor linear power supply for more than 30 years. The power supply circuitry consists of a 220/2 * 18v / 3.5a transformer, a rectifier, a smoothing filter, a power amplifier, lm301, and two regulators lm317 and dc power supply: The circuit is built using chip tl494, and will give you approximately 200w. The block diagram of a linear power supply is as shown in the following figure.
