摘要

本文提出了一种带电容输出滤波器的全桥升压lcl型dc/ac/dc变换器，输出电压恒定。当输入电压发生变化时，频率随着晶体管关断时间的恒定而变化，以保持输出电压恒定。基于这一思想，构建了一个50 ~ 100V直流输入、100 ~ 120khz、400 ~ w、200v直流输出的变换器，并利用傅立叶数学描述来帮助设计。最后，给出了400-W功率实验样机的实现报告。

A Full-Bridge Boost LCL-Type DC/AC/DC Converter

This paper presents a full-bridge boost LCL-type dc/ac/dc converter with a capacitive output filter and operating with a constant output voltage. When the input voltage has changed, the frequency changes with a constant turn-off time of transistors to keep the output voltage constant. Based on this idea, a 50 to 100V dc input, 100-120kHz, 400-W, 200-V dc output converter has been built, and a fourier’s mathematical description is exploited to help the design. Finally, a report on the implementation of a laboratory prototype with 400-W power is presented.
