CHARGER/DISCHARGER, DISPLAY, PLASMA DISPLAY PANEL AND CHARGING/DISCHARGING METHOD

摘要

A charger/discharger (602) charging/discharging a charge/discharge object capacitance (Cp) by applying a predetermined voltage thereto. The charger/discharger comprises an electric energy collecting capacitor (Cr) having a capacity not higher than the charge/discharge object capacitance and connected with a common conductor at one end, a first path forming means (D1, SW1) having one end connected with the other end of the collecting capacitor and the other end connected with the charge/discharge object capacitance for charging the charge/discharge object capacitance through a resonance inductance (L), and a second path forming means (D2, SW2) having one end connected with the other end of the collecting capacitor and the other end connected with the charge/discharge object capacitance which is caused to discharge through the resonance inductance (L) for collecting electric energy to the collecting capacitor.
