Abstract

This paper considers the control of a series active filter integrated with a double-series diode rectifier. It is shown that, as result of delays introduced by digital control, current-mode control is preferred to voltage-mode control for digital implementations. A Fourier-based method for generating balanced current references with optimized power factor is presented. The advantage of current-mode control is illustrated by simulation and the Fourier-based method is verified by experiment.
