Abstract
An energy recovery apparatus for a plasma display panel is provided that may include a capacitor equivalently formed at a discharge cell, an inductor, an energy recovery capacitor, switching units and a voltage sustain diode. The inductor may form a resonance circuit together with the capacitor. The energy recovery capacitor may recover energy of the capacitor thus to be charged. The switching units may be installed between the capacitor and the energy recovery capacitor, for controlling a charging/discharging of the capacitor. The voltage sustain diode may be installed between the inductor and a ground voltage source, for preventing a voltage between the inductor and the capacitor from being dropped to a voltage less than a ground voltage.
