摘 要: 随着电力电子技术的发展,开关电源的应用越来越广泛。反激式变换器以其设计简单,体积小巧等优势,广泛应用于小功率场合。其中,高频变压器承担了传递功率、隔离等作用,是设计中极为关键的一环。介绍TOPSwich-GX系列芯片的工作原理,并以一个基于它的单输出反激式变换器为例,详细阐述了高频变压器设计的原理和步骤,对设计实践有很好的指导意义。 With the development of power electronics technology,switching power supply are used more and more widely. The fly - back converter with advantages of easily designed and small volume widely applies to low - power occasions. The high - frequency transformer which is very important in the design takes the role of power transmission and isolation. The working principle of TOPS- witch - GX Family is introduced,and a single output fly- back converter based on it is taken for example to expound the principle and steps of high- frequency transformer design, which are good guides for practice.
