Abstract

This paper describes a completely digitally controlled low-harmonic rectifier. It is shown that the dynamics of the outer voltage loop can be significantly improved using a digital notch filter. Low input current harmonics and fast voltage response are experimentally verified using a 200 W universal-input boost power supply operating at the switching frequency of 200 kHz.
