Several-hundred-kHz single-phase to commercial frequency three-phase matrix converter using delta-sigma modulation with space vector

This paper discusses the pulse density modulation (PDM) control methods for a single-phase to three-phase matrix converter (MC) in the high-frequency application. This converter outputs a commercial power grid frequency, i.e. 50 Hz or 60 Hz from the input of several-hundred-kHz frequency. The proposed circuit achieves zero voltage switching operation by using the PDM control method. In this paper, two PDM control strategies are compared between a conventional PDM control method based on space vector modulation (SVM) and the proposed PDM control method, which is combined with SVM and a delta-sigma conversion. Also, the experimental results of the proposed control method will be demonstrated and discussed. As a result, the total harmonic distortion (THD) of the output voltage with the proposed PDM control method is improved to 1.87% from 9.05% of the conventional PDM control method.
