Power Supply – Block Diagram (AC – DC conversion process)

Many electronic circuits need a direct current (DC) voltage source, but what we commonly find are voltage sources of alternating current (AC). In order to achieve a direct current voltage source, the alternating current input must follow a conversion process.

How does a battery work?

The electric current is a flow of electrons that flow through a conductor cable. Electrons are negatively charged, and like two magnets that we want to put together, negative side with negative side or positive side with positive side, they repel.
