Description
Summary:SUMMARY This paper proposes a pulse current generator operated in discontinuous conduction mode for driving a tubular field emission lamp (TFEL). The proposed system based on flyback topology can provide pulse power driving to eliminate the temperature rise and arcing phenomenon caused by the traditional constant voltage driving. Therefore, both the lighting efficiency and lamp lifespan are improved. In this paper, an equivalent model of the TFEL is constructed to exhibit its capacitive characteristics. Moreover, the circuit configuration and each operation mode in a switching cycle are also described. And then a complete design considerations and mathematical model are discussed in detail. All the experimental results agree with the computer simulations to verify the theoretical predictions. Copyright © 2011 John Wiley & Sons, Ltd. This paper implements a pulse current generator operated in discontinuous conduction mode for driving a tubular field emission lamp. The proposed system based on flyback topology can provide pulse‐type power driving to eliminate the temperature rise and arcing phenomenon caused by the traditional constant voltage driving. Therefore, both the lighting efficiency and lamp lifespan are improved. Copyright © 2010 John Wiley & Sons, Ltd.
