摘要
数字控制的模块电源具有高效率、高功率密度等诸多优点,是当前电源技术的研究热点。分析了TI公司最新推出的隔离型电源专用数字控制芯片UCD3138的特点,并以其为控制环路核心,设计了一款带同步整流的数字控制全桥DC/DC变换器。最后搭建模块电源样机,验证了设计的有效性,电源峰值效率可达94%以上。
This paper analys the features of highly integrated digital controller UCD3138 for isolated power launched by TI recently.A digital controlled full-bridge DC / DC converter with synchronous rectifier based on UCD3138 is designed.The real prototype is fabricated,and the experimental results verified the rationality of design method.High efficiency up to 94% can be obtained.
