Abstract

A power factor correction (PFC) circuit is described which includes an inductor configured to generate an output voltage to an output load, an output voltage sensor, an output current measurement circuit, a first filter capacitor coupled between the output voltage and a first input node, a second filter capacitor between the first input node and a low voltage, and a first input node voltage sensor. Capacitor compensation logic is configured to receive the output current and the first input node voltage, to compensate the output current for the first filter capacitor and the second filter capacitor using the first input node voltage, and to generate a corrected output current. A control system is coupled to receive the output voltage and the corrected output current and configured to generate control signals to control the output voltage.
