This paper proposes a novel control strategy for a matrix converter, which features direct instantaneous active‐ and reactive‐power control of the converter. The theoretical aspects of the proposed control are discussed, and computer simulation results are presented to confirm the basic controllability of the technique. In addition, several operational characteristics were examined through experimental tests, using a 1.5‐kW prototype. The maximum efficiency and the total input power factor of the prototype with a 30‐Hz output frequency were 95.4% and 99.9% at 1.5‐kW load, respectively. The total harmonic distortion at the rated load was 5.9%. These results demonstrate the feasibility and effectiveness of the proposed strategy. © 2009 Wiley Periodicals, Inc.
