Distributed Power System for Driving SD 42 PDP Television

Abstract

The 440 W distributed power system(DPS) is developed for driving PDP(SD42") TV. The half bridge ZVS PWM converter is used in sustain, set and reset for reducing the losses. All of 15 output powers are designed. Each electrode is supplied by these powers. In this system, mainly outputs are Va for address, Vs for sustain, Vset for set up, Ve for reset and Vscan for scan voltage. The experimental results including steady state response and transient response are obtained for these outputs. The measured maximum efficiency through the DPS developed is about 91% in case of 220 V input and full load. And the efficiency of the sustain voltage(Vs) is up to 95.27%.
