Abstract
An auxiliary power circuit may measure a first time during which the voltage level of a capacitor falls from a first level to a second level by a leakage current of the capacitor, may charge the capacitor to a third level, may measure a second time during which the voltage level of the capacitor falls from the third level to a fourth level by the leakage current of the capacitor and a discharge current of a current source, may calculate a capacitance of the capacitor based on the first level, the second level, the first time, the third level, the fourth level, the second time and the discharge current of the current source, and may determine the state of the capacitor based on the calculated capacitance of the capacitor.
