Abstract: An active capacitor discharge tool may include circuitry for efficiently discharging a capacitor. The active capacitor discharge tool may include batteries (or regulated voltage sources) for actively discharging a capacitor using multiple discharge paths. The active capacitor discharge tool may alternatively short the capacitor to a ground connection using the multiple discharge paths based on a timing associated with a clock frequency of a clock signal. Discharging a capacitor by alternatively grounding the capacitor using different discharge paths may distribute a generated discharging heat and may discharge the capacitor faster. Moreover, when a capacitor includes stored electrical charges corresponding to a capacitor voltage lower than a sufficiently discharged voltage to enable an operator to handle the capacitor, the active capacitor discharge tool may short an anode and a cathode of the capacitor to discharge the capacitor to the ground connection voltage level.
