Abstract

A high-frequency (HF) ac linked universal converter is proposed for distributed generations interfacing three-phase ac with single-phase ac or dc. The primary and secondary of the HF isolation transformer are, respectively, formed by a three-to-single-phase matrix converter and a cyclo converter. Based on the operating principle, a general and simple to be implemented space vector modulation (SVM) is developed from that for the conventional indirect matrix converter and constantly operated virtual dual-active-bridge converter. Simulation studies carried out on different amplitudes and frequencies of single-phase ac output and dc output demonstrate effectiveness and simplicity of the proposed converter with the SVM solution.
