Harmonic Elimination PWM

Selective Harmonic Elimination PWM for 3-Phase Inverters

Description

Selective harmonic Pulse Width Modulated Pulses are presented in this model. Six dominant harmonics are removed in this simulink model which are present in three-phase PWM inverter. See the FFT for the output voltage waveform and current waveforms. Interestingly you can see that 5th, 7th, 11th, 13th, 17th and 19th harmonic content is zero.

Mr Naveen.....
Hi......
I simulated ur ckt.....gud i got the output....
In the same, photo copy of FFT analysis was given and it shows 95% THD ....seems very high .......
As per IEC standards, it has to be <8% ..hence would suggest any ckt accordingly..........

Thank you
