  • ELECTRIC CHARGING/DISCHARGING APPARATUS, PLASMA DISPLAY PANEL, AND ELECTRIC CHARGING/DISCHARGING METHOD
    Publication number: 20090009430
    Abstract: A charging/discharging apparatus (602) for charging a capacitance to be charged/discharged (Cp) includes: a recovery capacitor (Cr1) for recovering electric energy which has one terminal connected to a first power supply (GND) through first switch means (SW11) and another terminal connected to a second power supply (Vs+Vo) through second switch means (SW12); first path forming means (D11) which has one terminal connected to a connection point between the second power supply and the other terminal of the recovery capacitor and another terminal connected to the capacitance to be charged/discharged, and charges the capacitance to be charged/discharged through a resonant inductor (L1) when the first switch means is turned on; second path forming means (D12) which has one terminal connected to a connection point between the first power supply and the one terminal of the recovery capacitor and another terminal connected to the capacitance to be charged/discharged, and discharges the capacitance to be charged/discha
