SUMMARY
The discussion centers on the acceptance of triple-n harmonics in the output voltage spectrum of Voltage Source Converters (VSCs) when utilizing Sinusoidal Pulse Width Modulation (SPWM) with a frequency modulation index that is a large odd integer multiple of 3. Participants clarify that in three-phase current systems, triple-n harmonics naturally cancel out, which is a key reason for their acceptance in this context. The acronym definitions for VSC and SPWM are also provided for clarity.
