摘要
本论文研究了一种含负压的多路输出电源,用于PDP显示器Y电极驱动电路中。该电源按照Y电极驱动的不同条件要求,利用反激式结构,采用主从形式,通过耦合在变压器中的不同匝比,实现三路不同输出。同时论文中还对单端反激式电源的工作原理及负压产生电路进行详细分析,研究了主输出回路对从输出回路的影响,并且通过相关测试进行验证。
A multi-output power supply which contains a negative voltage output is proposed. It is used in the Plasma Display Panel（PDP） for the Y electrode driving circuit. According to the working conditions in the circuit, it adopts the topology of flyback converter and uses a transformer with several coupling windings of different turns ratio in order to achieve three different voltage output. Moreover, the operational principle of the single-flyback converter and the negative voltage output circuit are presented. The paper also investigates the influence of the main output on the subordinative outputs. And the experimental results are listed at the end of paper to verify the proposed power supply.
