基于UCD3138的数字电源研究与设计
|
摘要
数字化是电子技术发展的一个重要方向,可以更高效安全的实现电力电子系统的稳定性和可靠性,并能满足人们对电子设备智能化的各种要求。UCD3138是TI公司生产的一款新型隔离数字电源变换芯片,以此芯片为控制环路核心,设计了一款全桥拓扑结构的数字电源控制器,实现了输入48VDC,输出12VDC电压变换。主要介绍了数字电源变换器的设计过程和软件控制方法,然后搭建400 W功率级实验样机,进行相关实验,最后给出实验波形,验证了设计的可行性。
Digitization is an important direction of the development of electronic technology,it can improve the stability and reliability of electronic system and can meet the various needs of electronic intelligent equipment.UCD3138 is an isolated power controller launched by TI company production,This paper designed a digital controlled full-bridge DC/DC converter based on UCD3138,achieving 48 VDC/12 VDC alternation.And this paper described the principle of this converter and software control method,then the real prototype of 400 Wpower levels is fabricated,finally,giving the experimental waveforms and verifing the rationality of digital control power based on UCD3138.
