Simple Power Supply Circuit Diagram With Explanation

But first i wanted to start by creating a simple circuit that converts from the main power voltage 220v or 110v to 5v.

Simple power supply circuit diagram with explanation.

Digital dc regulator if you are looking for 5v dc power supply for the digital. The output from an ordinary power supply is fed to the voltage regulating device that provides the final output. I have built many circuits in my life but this is actually the first time i ve built a power supply circuit from scratch. An essential part of an ac dc power supply circuit is the filter used to separate the residual ac called the ripple voltage from the dc voltage prior to output.

Before going to circuit diagram it is necessary to understand the operation of smps. As shown in the diagram the power supply to the load is through the switching circuit and therefore the power supply can be cut by keeping the switch open. In a linear power supply the power transistor is operated in a linear mode. It is quite easy to understand the working process of the switching power supply.
