Low cost IGBT-based single-sided plaina display panel driver

Abstract

Plasma display panel (PDP), has many desirable advantages over other display technologies and at the moment is expected to be the most promising flat panel display [1, 2], Due to the inherent capacitive characteristics between surface discharging electrodes X-Y and between opposed addressing electrodes within the PDP as well (fig. 1); high displacement current occurs during charging and discharging, causing a considerable energy loss [1-4]. Now, if an inductor is connected in series with the panel, then it can be charged and discharged through the inductor. Ideally, this would result in zero power dissipation since the inductor would store all the remaining energy in the panel and regenerate it back again [4], Typically, for this application, the previous circuit arrangement capacitor- inductor is called Energy-Recovery Circuit (ERC). Of course, this remedial strategy also suffers high stress and a high peak current in a real PDP drive. A new low cost full-soft switching approach IGBT-based, fulfilling the requirements for a Plasma Display driver and ERC schema is proposed. Simulation, experimental results based on a 42-inch AC PDP demonstrating the feasibility of such a structure, dynamics and total temperature-based looses [5-7], for an accurate benchmarking will be presented.
