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.
