摘要

本文研究了一种单输入双输出非隔离DC-DC变换器的拓扑结构、设计和控制策略。这种拓扑结构具有开关应力小、无源元件尺寸小、效率高等优点。在小信号模型的基础上，设计了一种闭环控制系统，以调节输出电压和电容器的电压平衡。基于SPICE进行了仿真分析。分析了该变换器在并网蓄电池同步充电系统中的应用范围。

A Study on a Compact Single Input Dual Output Non-isolated DC-DC Converter With Low Switching Stresses

This paper is a study on a single input dual output non-isolated DC-DC converter topology, its design, and its control strategy. This topology has the benefits of low switching stress, reduced passive component sizes and high efficiency. A closed-loop control system has been designed based on a small-signal model derived in order to regulate the output voltages along with the capacitors’ voltage balancing. SPICE based simulation is carried out for analysis. Scope of this converter in the application in grid connected systems with simultaneous battery charging is also analyzed.
