Technical Examples

A driving apparatus of a plasma display panel includes an energy recovery circuit. The energy recovery circuit recovers charging/discharging energies of a panel capacitor to a power source supplying unit using a transformer according to charging/discharging operations of the panel capacitor. It includes a first controlling switch, a second controlling switch, and a transformer. The second controlling switch is connected between the panel capacitor and the power source supplying unit and switched according to an external control signal to control the energy recovery from the panel capacitor to the power source supplying unit. The first controlling switch is connected between the panel capacitor and the power source supplying unit and switched according to an external control signal to control the energy recovered in the power source supplying unit to be supplied to the panel capacitor. The transformer is connected between the first controlling switch and the second controlling switch and the panel capacitor so that resonance current flows on a primary inductor by the switching operations of the first controlling switch and the second controlling switch, and induced current induced by the resonance current flowing on a secondary inductor flows to a direction compensating the resonance current through the first controlling switch and the second controlling switch.
