Abstract: An energy recovery circuit for a plasma display panel charges a panel capacitor using energy within an inductor and recovers the energy from the panel capacitor. The energy recovery circuit supplies the panel capacitor with a clamping voltage enabling a potential of the panel capacitor to be constantly maintained. A controller controls the energy recovery circuit to supply the clamping voltage to the panel capacitor within a period taken to discharge a current of the inductor from a maximum value to a current level greater than zero. The charging timing point of the panel capacitor occurs prior to the current IL of the inductor L being discharged to zero and/or prior to the panel capacitor Cp being charged up to the sustain potential Vs.
