Haha, some of the analysis is not quite accurate. The AI-generated output includes an additional feature that allows users to provide original signals. The original signal is a sine wave with a minimum value of -100 V and an average value of 0 V. This indicates:
The peak (amplitude) is 100 V (because the difference between the average value and the minimum is 100 V).
The title states: Negative half-cycle polarity reversal:
This means inverting the negative half-cycle of a sine wave to become positive, which results in a full-wave rectifier (where the entire waveform is above the horizontal axis).
Valid value（RMS）The calculation involves taking the square root of the average value.
The effective value formula for the original sine wave is Peak Value / √2, which is approximately 100 / √2 ≈ 70.71 V.
The square of the waveform after full-wave rectification is the same in each half-cycle (simply flipping the negative half-cycle, but the squared value remains the same). Therefore, the average of the entire cycle's square and the original sine wave are identical.
Therefore, the effective value is 70.71 V.
