Greetings, iam Woodrow Beck, Have a blessed day.

What Is Third Harmonic Injection? [Solved]

3.2 VSI with Third Harmonic Injection Pulse Width Modulation The sine PWM method approaches less of maximum achievable output voltage. Hence, by simply adding third harmonic signal in low frequency sinusoidal reference signal, we can achieve the amplitude increase in output voltage waveform.

Next, we will study about
