The square wave operation of 3 phase VSI lines contains the harmonics. The amplitudes are____________?
Correct answer: B. Inversely proportional to their harmonic order
- A. Directly proportional to their harmonic order
- B. Inversely proportional to their harmonic order
- C. Not related to their harmonic order
- D. None of these
Explanation
For a square wave, the magnitude of each present harmonic is proportional to 1 divided by its harmonic order, so higher-order harmonics have smaller amplitudes.
