Abstract: This paper concentrates on evaluating performance of three phase z-source matrix converter (ZSM). The proposed converter is used in permanent magnet synchronous generator (PMSG) based 2.5 kW wind energy system. The proposed WES output supply frequency changes with respect to the change in wind velocity. The main objective of this ZSM 16nverter is to maintain constant frequency and constant load voltage when WES frequency changes with 16nd speed. It also reduces the power loss during low wind velocity and also due to total harmonic distortions (THD). In this work, the ZSM converter performance parameters like output voltage fi16uency, voltage magnitude, THD level are analyzed for various wind velocities and switching frequencies. The Sinusoidal pulse width modulation (SPWM), and modified carrier PWM schemes are used to control the matrix converter and results are to compare the evaluated parameters of the ZSM converter.
Keywords: z-Source Matrix Converter (ZSM), Permanent Magnet Synchronous Generator (PMSG), Total Harmonic Distortions (THD).
