Abstract
The switching power loss due to the panel capacitance during sustain period in AC PDP driving system can be minimized by using the energy recovery circuits. We have proposed a series CLC resonance type ERC (energy recovery circuit), SER1 (Seoul National University Energy Recovery circuit 1st). A load capacitance model was arranged for AC PDP, and the different capacitive load characteristics for the different sustain waveforms were explained. We also arranged the design procedure for SER1, and the experimental circuit was made by this guide. The experimental results of its application to a 42-inch surface discharge type AC PDP full module showed good performance of SER1 in energy recovery rate, which was measured up to 92%.
