Abstract
Provided is a switching mode power supply circuit for plasma display panel, which includes an EMI filter unit, a PFC unit, an output unit, and a standby unit. The EMI filter unit may include a first line filter connected to a commercial line input power, a first capacitor and discharge resistor connected to the first line filter, a second line filter connected to the first capacitor and discharge resistor, a second capacitor connected to the second line filter, and a relay unit disposed between the first line filter and the first capacitor and discharge resistor. The standby unit may be connected to a contact point of the first line filter and the relay unit.
