MATLAB Simulation of Two-Stage Matrix Converter

This paper presents a MATLAB simulation methodology for two-stage matrix converters, further validating the fundamental principles of this converter topology. During the simulation process, we incorporated multiple operational factors including input voltage characteristics, output voltage requirements, frequency modulation parameters, and switching patterns to comprehensively analyze the performance characteristics of the two-stage matrix converter. The implementation involves modeling power electronic switches using Simulink components and developing control algorithms for proper switching sequence generation. Furthermore, we provide detailed explanations and discussions of simulation results, including waveform analysis and performance metrics calculation, to facilitate better understanding of the converter's behavior. Through this study, readers can gain deeper insights into the working mechanism of two-stage matrix converters and master the methodology for conducting simulation analysis using MATLAB's Power Systems toolbox and custom control function implementations.
