About this manual

This document describes a power factor corrector (PFC) preregulator application tailored to supply a three-phase inverter for motion control. The design targets a mains supply of 220Vac (20%) at 50/60Hz, producing an output voltage of 440Vdc with a power output of 1500W. A switching frequency of 60kHz was chosen to balance magnetic size and switching losses.
