Abstract
This paper proposes a novel control strategy of a matrix converter, which features direct instantaneous active- and reactive-power control of the converter. A theoretical aspect of the proposed control is discussed, and some computer simulation results are presented to confirm the basic controllability of the technique. In addition, several operation characteristics are examined through experimental tests, using a 1.5-kW prototype. The maximum efficiency and the total input power factor of the prototype were 95.4% and 99.9% at 1.5-kW load with 30-Hz output frequency, respectively. Furthermore, the total harmonic distortion at the rated load was 5.9%. These results prove feasibility and effectiveness of the proposed strategy.
