3 Phase VSC SPWM (Triple-n harmonics)

Why is it that we accept triple-n harmonics in the output voltage spectrum of VSCs?

Assume we are using SPWM where the frequency modulation index is selected to be a large odd integer multiple of 3.

Thanks again!

Sorry I don't understand the acronyms.

In case this is three-phase current, triple-n harmonics cancel out naturally.

Sorry about the acronyms, I thought they were commonly used.

VSC = Voltage Source Converter

SPWM = Sinusoidal Pulse Width Modulation

Can you explain further how the triple-n harmonics cancel out naturally? And by "triple-n" do they just mean the harmonics that are integer multiple of 3?
