Comparative loss analysis and efficiency performance of resonance-based PDP sustain drivers

Sustain drivers based on the LC resonant operation have a significant influence on the entire circuit efficiency and cost of plasma display panels (PDPs). Although circuit efficiency of PDP drivers is extremely important, theoretical loss analysis and comparative studies of the sustain drivers have been missed in the literature, despite a variety of developed PDP sustain drivers. This paper presents in detail theoretical analyses and systematic comparisons of semiconductor losses in the PDP sustain drivers, including the inevitable conduction losses by the displacement currents, the undesirable extra conduction losses, the switching losses by the forced current commutations and the switching losses by the step voltage changes. Based on derived theoretical analysis and comparative features, sustain drivers are evaluated in terms of PDP operating speed as well as circuits' efficiency.This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIP) [NRF-2014R1A2A2A01006684], the Human Resources Development Program [20124030200060] of the Korea Institute of Energy Technology Evaluation and Planning, and a grant [14RTRP-B067916-02] from Railroad Technology Research Program funded by Ministry of Land, Infrastructure and Transport of Korean government
