Saturation voltage
The text under the image at the top of my post reads "Adding full saturation at the set voltage boosts the capacity by about 10 percent but adds stress due to high voltage" I don't understand why this would add extra stress when according to the charging graphs the voltage during the CV charge cycle is the same as the charger cutoff voltage.CT secondary current diagram. Second step is to determine the slope (1/S) of the upper part of the saturation curve, being careful that the curve is plotted on log-log scales with the decade spacing equal on both axes. “S” is defined as the reciprocal of this slope. You should get a slope such that S is in the neighborhood of 15 < S < 25.

Saturation current. The saturation current (or scale current ), more accurately the reverse saturation current, is the part of the reverse current in a semiconductor diode caused by diffusion of minority carriers from the neutral regions to the depletion region. This current is almost independent of the reverse voltage.১২ মার্চ, ২০২০ ... ... voltage of CT secondary results in a 50% increase in secondary current.
