Abstract
This paper introduces a dimmable electronic ballast for HPS lamps which uses a new strategy to implement the variation of the lamp´s power, based on the variation of the switches´ duty cycle. The complete operating principle, theoretical analysis and relevant equations are presented in this paper. The experimental results of a 70 W electronic ballast operating at 33 kHz switching frequency are also presented.
