Abstract
The present invention discloses an energy recovery sustain circuit for an AC plasma display panel in which includes one energy recovery sustain circuit incorporating X and Y electrodes. The invention includes a load capacitor, first and fourth switching elements to charge the load capacitor up to a predetermined positive voltage, a second and third switching elements to charge the load capacitor up to a predetermined negative voltage, a fifth switching element to apply an external voltage to the load capacitor to continually sustain the predetermined positive or negative voltage in the load capacitor during a certain period, an inductor for generating the certain leveled positive or negative voltage to charge the load capacitor, and first and second capacitors for charging or discharging a current flowing through the inductor. The invention has a simplified configuration, low production cost, and high reliability.
