Switching Power Supply Schematic. These are dc switching power supplies. Its construction is typical for a modern computer psu with mosfet switches and active power factor correction pfc.
Note that most schematics circulating on the internet depict old style psu with bipolar transistors and without pfc. Principle of input circuit and common circuit 4 1 principle of ac input rectification and filtering circuit. Simple switching power supply mains operated power.
On the portrayed power supply the circuit used was a stps30l30ct supporting up to 30 a.
Note that most schematics circulating on the internet depict old style psu with bipolar transistors and without pfc. The most commonly used type of power supply circuit is the smps switching mode power supply you can easily find this type of circuits in your 12v adapter or mobile laptop charger. Simple switching power supply mains operated power. In this project we will show how to build a switch mode power supply circuit with a mc34063 chip.
