摘要： 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.

摘要： Sustain electrodes (X1, X2, . . . ) of a PDP (20) are grounded. A PFC converter (40) converts an alternating voltage into a DC voltage (Vs) and applies it directly across a PDP driver (10). A sustaining pulse generating section (1) converts the DC voltage (Vs) into a primary voltage pulse (VF), and applies it across a primary winding (2a) of a transformer (2). The transformer (2) converts the primary voltage pulse (VF) into a sustaining voltage pulse (Vp), and applies it to scan electrodes (Y1, Y2, . . . ) of the PDP (20) through a reset/scanning pulse generating section (3). An inductor (L) is connected in parallel with a secondary winding (2b) of the transformer (2). The inductor (L) resonates with the panel capacitance of the PDP (20) at the rising and falling edges of the sustain voltage pulse (Vp).
