A Low-harmonic Control Method of Bi-directional Three-phase Z-source Converters for Vehicle-to-Grid Applications

Project Code :TEMAPE257

Objective

The main objective of this project is to develop a control method of bi directional z source converter with reduces harmonic distortions in the converter output, especially for vehicle to grid applications

Abstract

In this paper proposes for three-phase Z-source converters are proposed and investigated. The best performed one is further developed to a closed-loop PI control method. While the voltage conversion ratio is flexible, the output voltage Total Harmonics Distortion (THD) is below 3% within the voltage ratio range of 0.5 to 2.5. The effectiveness of the proposed method has been fully validated in MATLAB/Simulink simulations and RTLAB Hardware-In-Loop (HIL) experiments based on the real time simulator OPAL-RT OP4510. Compared to existing control methods, the proposed one performs better with reduced harmonics, flexible voltage gain, and simpler control algorithm. Analyzed using MATLAB Simulink software.

Keywords Z-source converter, Bi-directional converter, shoot-through states, voltage harmonics, (closed-loop control.)
