电子式电灯整流器的设计指南AN1543/D Electronic Lamp Ballast DesignPrepared by: Michal Bairanzade Power Semiconductor Applications Engineer Motorola SPS Toulouse http://onsemi.comAPPLICATION NOTEABSTRACT With a continuous growth rate of 20% per year, electronic lamp ballasts are widely spread over the world. Even though the light out of a fluorescent tube has a discontinuous spectrum, the higher efficiency brought by the electronic control of these lamps make them the best choice to save the energy absorbed by the lighting systems. A few years ago, the lack of reliable and efficient power transistors made the design of such circuits difficult! Today, thanks to the technology improvements carried out by ON Semiconductor, design engineers can handle all of the problems linked with the power semiconductors without s……
