A PAM Control Method for Matrix Converter Based on Virtual AC/DC/AC Conversion Method

IEEJ Transactions on Industry Applications, 2006
AbstractIn this paper, a novel control method for a matrix converter is proposed. The proposed method is a PAM (Pulse Amplitude Modulation) control method based on a virtual AC/DC/AC conversion method. Output voltage amplitude is controlled by controlling a virtual DC link voltage with a virtual rectifier.
