The input current waveform of a bridge controlled rectifier when the load is perfectly filtered is___________?
Correct answer: B. Square wave
- A. Sine wave
- B. Square wave
- C. Saw - tooth wave
- D. Trapezoidal wave
Explanation
With a perfectly smoothed load current, each bridge pair conducts for approximately half a cycle, so the source current reverses abruptly between positive and negative constant levels. This gives an ideal square-wave input current.
