SPWM technique for Three Phase Inverter. Analysis fundamental improvement with respect to modulation index variation is done in simulation. Analysis can be done also for switching frequency variation for shifting the dominant harmonics

基于MATLAB平台的PWM调制正弦波的快速傅里叶分析-his model simulates and computes Fourier analysis of PWM based sinusoidal waveform. Fundamental frequency can be changed in model properties. Amplitude modulation index and frequency modulation index can be adjusted in Sim
