A Single-Phase To Three-Phase Power Conversion System with Parallel Rectifier and Series Inverter

Abstract

This project presents a single-phase to three-phase power conversion system with parallel rectifier and series inverter to cope with single-phase to three-phase asymmetry. Such converter guarantees both reduction in the input current processed by rectifier circuit (due to the parallel connection) and reduction of the output voltage processed by each  inverter (due to the series connection). It is worth mentioning that, in spite of proposing a topology with features not yet observed in the technical literature, this paper presents a comprehensive model of the proposed converter, modulation strategy, and a general comparison with the conventional configuration. In extension we proposed FUZZY controller and Simulated results are also presented.
