PROBLEM TO BE SOLVED: To provide a plasma display panel drive device and method, and especially to provide a plasma display panel drive device and method for simplifying a sustain circuit contributing to light emission and power consumption of a plasma display panel, and for improving electric power recovery rate. SOLUTION: In this drive device, the circuit configuration and switching sequences of the sustenance circuit of a PDP(plasma display panel) drive circuit are designed in order to minimize a transitional period when the inductance current of a electric power recovery circuit is increased at charging and discharging of a PDP. As a result, not only the effect of the recovery rate of reactive power is improved and the effect of EMI(electromagnetic interference) is reduced by making switching loss to be zero, but also the effect of the number of circuit elements is reduced, as compared with that in the conventional PDP drive circuit are obtained in this drive circuit.
