Introduction

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 like the one shown in the picture below.

The picture shows the operation of a voltage power supply using a block diagram. The picture also shows the waveforms at the beginning (AC input), at the end (DC output) and between each of the blocks.

- The input signal which goes to the primary of the transformer is a sine wave and its amplitude depends on the country where we live (110/220 VAC or other). See the basic units of measurement in electronics.
