基于Simulink的SPWM三相逆变器仿真分析
Simulation Analysis of SPWM Three-phase Inverter Based on Simulink
摘要
Abstract
The three-phase inverter converts Direct Current(DC)into Alternating Current(AC)to provide a stable power supply for traction motors.The SPWM(Sinusoidal Pulse Width Modulation)control technique is used to generate pulse signals by modulating sinusoidal and triangular waves,thereby optimizing output waveforms.A simulation model that incorporates IGBT modules,DC power supply,three-phase loads,and an LC filter circuit is constructed.The output voltage waveforms,harmonic characteristics,and conversion efficiency under different conditions are analyzed.Results demonstrate that the LC filter circuit significantly improves output waveform quality,reducing the Total Harmonic Distortion(from 79.4%to 1.16%)while achieving high conversion efficiency.This study provides theoretical support for the stable operation of vehicle traction power supply systems.It should focus on further design optimization to adapt to complex operating conditions in the future.关键词
