電子鎮(zhèn)流器設計-electronic lamp ballast design

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
MOTOROLA, design engineers can handle all of the problems
linked with the power semiconductors without sacrificing the
global efficiency of their circuits.
This Application Note reviews basic electronic lamp ballast
concepts and gives the design rules to build industrial circuits.
