Abstract
A verification circuit for a capacitor power supply measures at least two voltages across the terminals of the capacitor at two points in time, the two points in time defining a time interval dT. A change in voltage dV over the time interval dT is determined. An operation powered by the capacitor is initiated, or not, by deriving from the time interval dT and/or the voltage change dV, a total required time or a total required voltage for completing the operation, and comparing the total required time or total required voltage to a pre-determined necessary total time or predetermined necessary total voltage, respectively (a 'time interval test').
