MATLAB Simulation of Three-Phase Inverter Space Vector Pulse Width Modulation Transformation

Through MATLAB simulation, we can effectively study and analyze the space vector pulse width modulation (SVPWM) transformation for three-phase inverters. SVPWM is a widely-used control technique that converts DC power supply to AC power supply. In the simulation process, we can model various input signals and parameter configurations to evaluate inverter performance under different operating conditions. The simulation approach typically involves implementing key algorithms including sector identification, switching time calculation, and PWM signal generation using MATLAB's Simulink environment or script-based programming. This methodology helps engineers and researchers better understand and optimize three-phase inverter operation principles, providing guidance and improvement directions for practical applications. The code implementation may include functions for Clarke transformation, reference vector calculation, and duty cycle computation for different voltage vectors.
