In an inverter with fundamental output frequency of 50 Hz, if third harmonic is eliminated, then frequencies in Hz of other components in the output voltage would be
- A. 250, 350, 500, high frequencies
- B. 250, 350, 550, high frequencies
- C. 50, 100, 350, 550
- D. none of these
Answer: B. 250, 350, 550, high frequencies
Explanation: With 3rd harmonic eliminated in a 50 Hz inverter, remaining odd harmonics are 5th (250 Hz), 7th (350 Hz), 11th (550 Hz), and higher.
