A Cost-Effective Energy-Recovering Sustain Driving Circuit for ac Plasma Display Panels

摘要

A new sustain driving circuit, featuring an energy recovering function with simple structure and minimal component count, is proposed as a cost-effective solution for driving plasma display panels during the sustaining period. Compared with existing solutions, the pro posed circuit reduces the number of semiconductor switches and reactive circuit components without compromising the circuit performance and gas discharging characteristics. In addition, the proposed circuit utilizes the harness wire as an inductive circuit component, thereby further simplifying the circuit structure. The performance of the proposed circuit is confirmed with a 42-inch plasma display panel.
