    • Pulse generating sections (1X, 1Y) convert a DC voltage (Vs) into voltage pulses (Vp), and apply the pulses to the sustain and scan electrodes (X, Y) of a PDP (20). Recovery switching devices (Q3X, Q4X, Q3Y, Q4Y) of power recovery sections (2X, 2Y) are turned on and off under the rising and falling edges of the voltage pulses (Vp), thereby connect recovery inductors (LpX, LpY) to recovery capacitors (CX, CY). Then, the recovery inductors (LpX, LpY) resonate with the panel capacitance (Cp). While the amounts of the resonance currents (ILX, ILY) are small, the inductances of the recovery inductors (LpX, LpY) are high. When the amounts of the resonance currents (ILX, ILY) exceed a threshold value, the inductances of the recovery inductors (LpX, LpY) are reduced.

    • A PDP driving circuit and a plasma display apparatus with high image quality are realized. The PDP driving circuit of the present invention has a function of lowering the voltage of a recovery capacitor by connecting a step-up circuit including at least an inductor, a switch element, and a diode to the recovery capacitor, and regenerating the excessive voltage of the recovery capacitor to a sustain voltage power supply. Since the luminance can be lowered even in time of light load with low lighting rate by lowering the voltage of the recovery capacitor in time of low lighting rate, a high tone image display is realized, and the PDP driving circuit and the plasma display apparatus with high image quality are realized. In the data electrode driving circuit with slower write timing, the write operation is stabilized by raising the voltage of the recovery capacitor, whereby the PDP driving circuit and the plasma display apparatus with high image quality are realized.
