AC DC Converters

1. What are AC DC Converters?

An AC/DC converter is a circuit that converts alternating current (AC) input to direct current (DC) output. AC/DC converters are also called “rectifiers”; they convert the input AC voltage into a variable DC voltage, which is then optimized through a filter to obtain an unregulated DC voltage.

 

2. How do AC DC Converters Work?

An AC DC converter works by converting alternating current (AC) to direct current (DC). This is accomplished through a process called rectification, which involves passing the AC current through a series of diodes that allow current to flow in only one direction, resulting in unidirectional current flow. The output of the rectifier is then filtered through capacitors and inductors to smooth the current flow and remove any residual AC component. Finally, a voltage regulator is used to regulate the output to ensure it remains constant.

4. What are AC DC Converters Used for?

AC DC converters are used in computers, TVs, mobile phone chargers, and other consumer electronics. They are also used in medical, military, and telecommunications equipment; kitchen appliances; industrial machinery; and commercial products using DC motors.
