Abstract
A speedy discharging circuit is applied to a power supply. The speedy discharging circuit is electrically connected to the power supply. The power supply includes a power output side and an output side capacitor. The output side capacitor is electrically connected to the power output side. The speedy discharging circuit includes an energy consuming unit, a switch unit and a switch control unit. The energy consuming unit is electrically connected to the power output side and the output side capacitor. The switch unit is electrically connected to the energy consuming unit. The switch control unit is electrically connected to the switch unit. When the switch control unit receives a sleep signal, the switch control unit turns on the switch unit, so that the output side capacitor discharges to the energy consuming unit.
