Explanation
The peak factor, or crest factor, is the ratio of the peak value of a waveform to its RMS value. The half-wave rectified sine wave has the highest peak factor compared to square, sine, and triangular waves because its RMS value decreases more significantly than its peak value, resulting in a larger ratio.
