摘要
单端反激变换器是应用较广泛的一种拓扑形式,基于LD7550B的反激变换器具有许多优良的特点。变压器设计是开关电源设计的一个非常重要的组成部分,通过10W功率变换器的设计可以基本掌握LD7550B的用法,开关电源中PCB的设计对电源的性能至关重要,通过反激变换器的一些实测波形对于设计类似的开关电源有一定的指导作用。
The single-ended flyback converter is a widely used topology method,and the flyback converter based on LD7550B has many advantages.The design of converter is very important for switch power supply design.Through the design of a 10 W power converter,we can basicaly learn the useage of LD7550B.The PCB design of switch power supply is important to the power supply performance.Actually measured wave form of flyback converter can be taken as a reference for design of similar switch power supplies.
