AC to DC Converter Circuit

There are mainly two types of converters widely used for AC-DC conversation purpose. One is the traditional Transformer-based linear converter which uses a simple diode bridge, capacitor, voltage regulator. Simple Diode Bridge can be constructed either with single semiconductor device like DB107 or with 4 independent diodes like 1N4007. The other type of converter is SMPS or Switch mode power supply which uses high-frequency small transformer and a switching regulator to provide DC output.

In this project, we will discuss traditional Transformer based design which use simple diodes and capacitor to convert the Alternating current into Direct Current and an optional voltage regulator to regulate the output DC voltage.
