Abstract
This paper verifies an isolated DC-AC power converter using a single phase to three phase matrix converter in experiment. A matrix converter does not require the large reactors and the large smoothing capacitors in a DC-link part. Furthermore, the proposed control method enables zero voltage switching of the matrix converter by implementing a phase shift control on the primary inverter and a pulse density modulation on the secondary matrix converter. In this paper, the fundamental operation of the converter is demonstrated by the experiment. From the experimental results, the total harmonic distortion in the output voltage is less than 5% in the entire range. In addition, a maximum efficiency of 90.9 % is achieved at an output power of 1.5kW.
