Abstract

<p>A modulation method, which consists of a conventional space vector modulation (SVM) method based on virtual AC-DC-AC conversion and a carrier signal modulation for matrix converters, was proposed by the authors, previously. The proposed SVM method can reduce the distortion of output voltage waveforms. In this paper, the proposed SVM method is explained. In addition, a mechanism for the suppression of output voltage distortion is examined by simulation. Specifically, this mechanism is clarified by the analysis of PWM patterns produced by the proposed SVM method. In addition, a mechanism for the suppression of voltage error is presented. The coincidence of simulation and experimental results confirms the validity of the simulation.</p>
