The ac output voltage waveform of VSI and AC output current waveform of CSI respectively is composed of___________?
Correct answer: D. High dv / dt, high di / dt
- A. High dv / dt, low di / dt
- B. Low dv / dt, low di / dt
- C. Low dv / dt, high di / dt
- D. High dv / dt, high di / dt
Explanation
A VSI produces a switched voltage with steep voltage transitions, giving high dv/dt, while a CSI produces a switched current with steep current transitions, giving high di/dt. Thus both waveforms have high rates of change.
