ABSTRACT:
Disclosed are an energy recovery apparatus and method for a plasma display panel. The energy recovery apparatus includes a sustain voltage source for supplying a sustain voltage, a panel capacitor formed equivalently at a discharge cell, a first charging circuit for forming a first charging path when one side of the panel capacitor is charged, a second charging circuit for forming a second charging path when the other side of the panel capacitor is charged, a first power circuit for supplying the sustain voltage to the panel capacitor and forming the first charging path, and a second power circuit for supplying a ground voltage generated from a ground voltage source to the panel capacitor and forming the second charging path. The energy recovery apparatus and method according to the present invention can decrease components in number and reduce power consumption and manufacturing cost by charging the other side of the panel capacitor using a charging voltage of one side of the panel capacitor.
