Abstract

The integration of a series active filter with a 12-pulse diode rectifier can provide an effective means for supply current harmonic free AC/DC conversion. Controlling the series active filter as a frequency selective impedance requires low delays and is not well suited for implementation by digital control. This paper suggests two control methods intended for implementation by digital control. The suggested current-mode control method for supply current balancing and voltage regulation is verified experimentally
