Abstract
Conventional PDP power system, which commonly uses two isolation transformer, consists of sustaining power ($V_S$), addressing power($V_A$), and Multi power($V_M$). Because each of these power conversion circuits use transformer and control IC, there are several defects: decrease of efficiency, rise of cost, and parts stress. This paper is proposed the method which operates PDP power system only with one transformer. The proposed method contributes not only to high-efficient performance of the DC/DC power stage and improvement of reliability but also to reduction of cost by reducing volume and size. Also, proposed method is proper to Address Display-period Separation(ADS) which is one of the driving methods of PDP. Superiority of the proposed method is proved by comparison with conventional method and theoretical, experimental analysis.
