Abstract

PDP driving circuit requires switching devices and capacitors to stand up high voltages over 160V. This is the main cause that the power consumption and the cost of a PDP driving circuit increase. Conventional PDP driving circuits consist of 3 voltage sources and 16 switching devices. In this paper, we propose a PDP driving circuit using 2 voltage sources and 12 switching devices that can be operated with a lower supply voltage than conventional driving circuit. The operation of the proposed driving circuit is verified by the computer simulation. Simulation results show that the output signal can drive PDP cell when the supply voltage is higher than 45V in the input frequency range 70kHz to 100kHz.
