PDP sustainers with reduced current stress and sensitivity to parasitic and distributed components

This paper presents three improved plasma display panel (PDP) sustainers with reduced current stress and sensitivity to parasitic and distributed components. In the paper, a useful cell equivalent circuit model is first introduced, and a widely used sustainer is then reviewed, on which three improved ones are proposed. The proposed sustainers can reduce currents through switches and sensitivity to parasitic and distributed components along its conduction paths. Derivation and operating principle of the proposed sustainers are addressed in detail. In addition, their related gaseous discharge mechanism in PDP cells is also presented. Hardware measurements have verified the feasibility of the proposed sustainers.
