Selective Harmonic Elimination PWM
This Simulink Model simulates a Selective harmonic elimination. Four dominant harmonics are removed in this simulink model which are present in single-phase PWM inverter. See the FFT for the output voltage waveform and current waveforms. Interestingly you can see that 3th, 5th, 7th, and 9th harmonic content is zero.
The angles are computed using the Newton Raphson Method (see File-->Model Properties -->Model Properties -->CallBacks-->InitFcn). To choose the modulation Index (Go File-->Model Properties -->Model Properties -->CallBacks-->InitFcn) and choose ii = (m)*10 - 1. ii = 91, it means m = 0.9;
