Apparatus for driving plasma display panel capable of increasing energy recovery rate and method thereof

1. Field of the Invention An apparatus for driving a plasma display panel (PDP), which is capable of simplifying the structure of a sustain circuit directly affecting the illumination and power consumption of the PDP and increasing an energy recovery rate, and a method thereof are provided. The structure and switching sequence of the sustain circuit are designed so that the transition time to increase the amount of current of an inductor in an energy recovery circuit when charging/discharging the PDP can be minimized. Accordingly, the recovery rate of displacement power can be increased, and EMI can be decreased by not causing switching loss. In addition, the number of circuits required in the apparatus for driving the PDP can be reduced smaller than the number of circuits required in a conventional PDP driver.
