The results have shown that the conventional model cannot represent the “capacitive” behavior (only the “resistive” behavior) of the MOSA, which occurs whenever it is excited by a voltage below of the rated voltage. Therefore the results of energy absorption at voltage operation were divergent. The results of energy absorption have shown good accuracy for both lighting current impulse and fast front surge. The values of residual voltages did not have good accuracy for fast front surges like lighting impulse current, because the conventional model does not include the dynamic effects of voltage-current characteristics of the MOSA.
