Tw o-pow er-stage power-factor-correct ion converter can be simplif ied to sing lestag e one w ith the development of charge pump pow er factor correct ion( CPPFC) . This paper invest igates the applicat ion of cont inuous input current CPPFC techniques in hig h intensity discharge lamp elect ronic ballast, w hich can decrease the component count and lower the cost. A dynamic model of high pressure sodium(HPS) lamp is proposed for further study of characterist ics of electronic ballast s w ith dif ferent pow er. Experiment and simulat ion results verify the feasibility of HPS lamp operat ing at high f requency. It is show n that the presented electronic ballast has 0. 97 pow er factor and 12% total harmonic distortion.
