Rectification. AC/DC converters serve as rectifiers. They convert ac to dc in a number of industrial, domestic, agricultural, and other applications. Rectifiers are used as stand-alone units feeding single and multiple dc loads and as input stages of ac systems because of their virtually unlimited output power and fine controllability.

For 230 V mains the DC output should be about 400 V. A large capacitor at the output does not affect the power factor, but is good for smoothing the DC voltage. An additional advantage of PFC circuit is the regulated DC voltage that gives the opportunity of having a following SMPS to be wide range operated (e.g. 110 V to 230 V input voltage).

Rectification Basics. The simplest rectifier is a diode connected to AC power supply. This is also known as a half wave rectifier.
