Harmonics in 3 phase inverters can be reduced by using___________?
Correct answer: C. Both passive and active filters
- A. Passive filter
- B. Active filter
- C. Both passive and active filters
- D. None of these
Explanation
Both passive LC filters and active filters can suppress inverter harmonics. Passive filters are simpler, while active filters generate compensating currents or voltages for more flexible cancellation.
