In a 3 phase CSI, if the required line output voltages are balanced and 120 degree out of phase, then the chopping angles are used to eliminate only the harmonics at frequencies
Correct answer: D. All of these
- A. 5
- B. 7
- C. 11
- D. All of these
Explanation
In a three-phase CSI, properly selected chopping angles can eliminate targeted low-order harmonics such as the 5th, 7th, and 11th. Therefore, all the listed harmonic orders can be addressed.
