AC DC Switching Power Supply

AC DC Switching Power Supply Design

This is an AC DC switching power supply circuit for those who want to engage in switching power supply design. It is designed using integrated circuits, Mosfet transistor, and you can learn to design a transformer in accordance with the desired.

The AC DC switching power supply project uses 117V AC power source and very easy to learn and with through the conversion process on the switching board will provide the DC output voltage.

AC DC Switching Power Supply Design Circuit

The AC DC switching supply designed using UC3843 IC and Logic MOSFET IRF740 and a few other passive components where UC3843 does not allow for feedback control of the output voltage. Design of power supply also comes with a PCB.

In the AC DC switching supply design, the output voltage is determined by the “Turn Ratio” of Transformer T1. Switching power supply is very useful and can be used almost continuously with the ability of 25W. Which means you can use it as a small power supply or a battery charger.

If indeed you want to engage further in the switching power supply, click on the image schematic and PCB and find the address that will take you to a site with some switching supply projects, the best I have ever found.
