Cost-effective energy recovery display driver for 42-inch plasma display panel (IECON ´04)

A new cost-effective energy-recovery circuit for a plasma display panel is proposed. Since it is composed of two small resonant inductors and four power diodes instead of the conventional large auxiliary circuit, it features a simpler structure, less mass, fewer devices, higher efficiency, and lower cost. Moreover, the very stable and uniform light emitted from a PDP proves the high quality of screen. Therefore, it is well suitable for hang-on-the-wall TVs which have the desirable features such as thinness, lightness, high efficiency, and low price, etc. To confirm the validity of the proposed energy recovery circuit, a comparative analysis and experimental results based on a whole AC PDP driver equipped with the proposed circuit for 42-inch PDP are presented.
