In single phase VSI, the harmonic which is not present is____________?
Correct answer: A. 2nd
- A. 2nd
- B. 3rd
- C. 5th
- D. 7th
Explanation
A single-phase VSI with the usual half-wave-symmetric square-wave output contains odd harmonics such as the 3rd, 5th and 7th, but its even harmonics, including the 2nd, are absent.
