Open-Loop Simulation Model for Indirect Two-Stage Matrix Converter

In this paper, we present an open-loop simulation model for an indirect two-stage matrix converter and demonstrate output results that align with theoretical derivations. The implementation utilizes S-function programming to achieve space vector modulation strategy, where the modulation algorithm is coded directly in MATLAB's S-function format for precise control of switching sequences and timing. We conducted a series of simulation experiments based on this model to verify its reliability and effectiveness. During these simulations, various operating conditions and parameter configurations were considered to comprehensively evaluate the model's performance characteristics. The simulation framework includes detailed implementation of the dual-stage conversion process, with the rectifier stage handling input voltage conversion and the inverter stage managing output waveform generation. Overall, our research provides valuable references and insights for further development in this field, particularly in power electronic converter modeling and control strategy implementation.
