Abstract
An energy recovery circuit for a plasma display panel (PDP) according to the present invention includes an energy recovery unit recovering and storing energy from the PDP; and a switching stabilizing unit electrically connected to the energy recovery unit to stabilize switching of a sustain discharge pulse applied to the PDP. The switching stabilization unit may include one diode, two switches and one capacitor for energy recovery, or include two switches and an external input voltage source that is an external voltage supply. According to the present invention, the difference of voltages applied to both drain and source terminals of a switch (SW) for applying a sustain discharge voltage (Vsus) is minimized at the time when the switch (SW) is switched, so that switching can be stabilized by preventing hard switching from being generated when the sustain discharge voltage is applied to a panel. Further, switching and electro-magnetic interference (EMI) noises of the circuit, generated due to the hard switching can be decreased, and therefore, driving reliability of the circuit can be improved.
