双极性模式下PWM逆变电路的MATLAB仿真与分析-电气工程综合训练报告

This report, entitled "Computer Simulation of PWM Inverter Circuit in Bipolar Mode" explores the application of PWM control technology in inverter circuits, with a focus on bipolar mode. PWM control technology is widely used in inverter circuits, with the majority of circuits currently in use being PWM-based inverters. The report begins by establishing the circuit model necessary for inverter control, utilizing IGBT as the switching device. It then analyzes the operating principles of single-phase bridge voltage-type inverter circuits and PWM control circuits. The simulation of the circuit is conducted using MATLAB's SIMULINK, and the final simulation waveforms are presented. The report includes a detailed overview of the inverter circuit, explanation of the main circuit operation principles, the design process, setting parameters for the simulation model, analysis of simulation results, and a conclusion. MATLAB, introduced by the American company Mathworks in 1983, is a high-performance software for numerical analysis and computation, continually improving its functionalities and versions. The report provides a comprehensive understanding of PWM inverter circuits in bipolar mode through mathematical modeling and simulation analysis.
