Abstract
A charging/discharging circuit of a plasma display panel (PDP) driver has a first inductance having a first end connected to the first side of the panel capacitor, a first diode having an anode coupled to a second end of the first inductance, a second diode having a cathode coupled to a cathode of the first diode, a second inductance having a first end coupled to an anode of the second diode and a second end connected to the second side of the panel capacitor, a third diode having a cathode coupled to the second end of the first inductance, a fourth diode having an anode coupled to an anode of the third diode and a cathode coupled to the first end of the second inductance, and a switch coupled between the cathode of the first diode and the anode of the third diode.
