Sustainer Circuit의 소모 전력 저감을 통한 AC PDP의 방전 효율 개선 방안

Abstract

This thesis proposes a method of improving luminous efficiency (EL) of plasma display panel. Inductors are inserted in series with SUS_UP switches for reducing turn-on hard switching losses of the switches. In addition proposed sustainer circuits lead dispersion of light emission for improving EL. Sustain pulses are applied by series resonance, thus panel’s voltage exceeds sustain voltage (VS). Therefore, parts of discharging currents leak into VS capacitors. To remove the leakage of discharging currents, current paths to VS capacitors are removed. The circuit was tested on a 50-inch FHD (1920×1080) single-scan AC PDP. Compared with the conventional method, EL was increased by 9.754 % for a full white pattern.
