Which statement is true regarding the inverter?
Correct Answer: C — The voltage waveform generated in a single phase system is symmetrical around the time axis and the odd harmonics are absent in the resulting pulse width modulated waveform.
In a single-phase PWM inverter, the output voltage waveform is symmetrical around the time axis, ensuring consistent positive and negative cycles. Due to this symmetry, odd harmonics cancel out and are absent in the PWM waveform, resulting in an output that closely approximates a pure sine wave.
