摘要
设计了一种多路隔离输出的车载辅助电源,采用UC3842控制芯片的多路输出反激变换器。结合试验样机和试验结果,分析了电路的工作特点、变压器的设计要求。该变换器的效率高、体积小、具有过载与短路保护等优点。
A muhiple isolated output flyback convener which uses UC3842 as control IC is designed for the vehicle auxiliary power supply. The internal circuit and characteristics are analyzed based on the prototype machine and the results about experimentation. The main process of the flyback transformer in prac, tieal design is described. Consequently, the advantages of this convener at high efficiency, small volume, strong ability of overload and short circuit, high reliability are presented.
