In this episode, we break down what Power Factor Correction (PFC) is actually doing inside an offline power supply. We will explain why bridge-rectifier front ends create distorted input current, how active boost PFC reshapes that waveform, and what engineers need to know about conduction modes, interleaving, EMI filters, and modern wide-bandgap topologies. It also connects classic PFC design practice with newer digital-control approaches in advanced energy systems.
