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 to a variable DC voltage, which is then optimized through a filter to produce an unregulated DC voltage.

 

2. How do AC DC Converters Work?

An AC-DC converter receives alternating current (AC) from a wall outlet and converts it to direct current (DC). It does this by first stepping down the voltage with a transformer, then rectifying it with a diode bridge, and finally smoothing the voltage with a capacitor. The converter’s output is a regulated, low-voltage DC power supply.

4. What are AC DC Converters Used for?

AC-DC converters convert the alternating current (AC) from the wall outlet into unregulated direct current (DC). These power supplies consist of a transformer (to change the voltage of the AC power passing through the wall outlet), a rectifier (to convert the AC power to DC), and a filter (to smooth out the noise from the peaks and valleys of the AC power).
