Design and Simulation of A Power Supply Based on A Matrix Converter Under Unbalanced Input Voltage

In this paper, design and simulation of a three-phase, 400 Hz power supply based on a matrix converter topology and its new control system are given. A new control method based on the direct modulation technique, which can perfectly work with input voltage unbalance, has been proposed. Theory analysis and simulation results for the proposed power supply are presented in the paper to demonstrate the performance of this control method under input unbalanced voltages. The simulation results show that output voltages unbalanced factor is decreased to 1% and their THDs are less than 2% which is an improvement compare to SVM and conventional direct modulation techniques.
