Abstract
An example method includes storing a peak voltage level, a valley voltage level, and a frequency of a signal that corresponds to an alternating current (AC) signal across a capacitor; periodically determining whether a current peak voltage level of the signal is different than the stored peak voltage level of the signal or a current valley voltage level of the signal is different than the stored valley voltage level of the signal; determining, based on whether the current peak voltage level of the signal is different than the stored peak voltage level or the current valley voltage level of the signal is different than the stored valley voltage level, whether the AC signal has been removed from the capacitor; and in response to determining that the AC signal has been removed from the capacitor, discharging the capacitor.
