MATLAB Code Implementation for Power Electronics Simulation

Power electronics is a crucial discipline focusing on electrical power conversion and control, where simulation technology serves as the foundation for electronics engineering education, making it particularly suitable for beginners learning fundamental principles. This article introduces the basic structures of power electronics simulations and provides detailed descriptions of the following techniques: Unipolar PWM, Bipolar PWM, Single-Phase Half-Wave, Single-Phase Semi-Controlled, Single-Phase Square-Wave Inverter, Single-Phase Fully-Controlled, Chopper Circuits, Three-Phase Semi-Controlled, Three-Phase Square-Wave Inverter, and Three-Phase Fully-Controlled. Through MATLAB implementations, you'll learn simulation techniques using key functions like PWM generation blocks, thyristor/gate control logic, and power converter modeling approaches. Each implementation demonstrates practical algorithm applications including switching frequency control, pulse width modulation techniques, and phase-angle coordination for multi-phase systems. The corresponding Pinyin-named files facilitate easy identification and study of different technologies, while the code structure helps understand advantages and limitations of each power electronics topology through comparative waveform analysis and performance evaluation.
