The THD of an inverter output waveform should be _________ to ensure proper operation of the load and to minimize electromagnetic interference.
Correct Answer: D — Very Low
THD measures harmonic distortion relative to the fundamental frequency. A very low THD means the output waveform closely resembles a pure sine wave, ensuring loads such as motors and transformers operate efficiently, minimizing EMI, and reducing thermal stress on components.
