Abstract
There is provided a circuit for discharging AC power including: a first rectifier rectifying AC power inputted from an AC power line; an electro-magnetic interference (EMI) removing unit installed between the AC power line and the first rectifier to suppress EMI of the AC power; a discharging signal generator generating a discharging signal from the AC power; and a discharging unit including a discharging resistor for discharging a voltage charged in the EMI removing unit according to the discharging signal, whereby standby power consumption may be reduced when the AC power is inputted and the voltage charged in a capacitor for removing EMI may be discharged to meet a predetermined safety standard when the AC power is blocked.
