电子镇流器设计-electronic lamp ballast designWith a continuous growth rate of 20% per year, electroniclamp ballasts are widely spread over the world. Even thoughthe light out of a fluorescent tube has a discontinuousspectrum, the higher efficiency brought by the electroniccontrol of these lamps make them the best choice to save theenergy absorbed by the lighting systems.A few years ago, the lack of reliable and efficient powertransistors made the design of such circuits difficult! Today,thanks to the technology improvements carried out byMOTOROLA, design engineers can handle all of the problemslinked with the power semiconductors without sacrificing theglobal efficiency of their circuits.This Application Note reviews basic electronic lamp ballastconcepts and gives the design rules to build industrial circuits.
