摘要

本文提出了一种新的非隔离高升压交错级联变换器。与传统的级联升压变换器相比，该变换器具有更高的电压增益、更低的输入纹波和更小的开关和二极管电压应力。此外，与传统的级联升压变换器不同，在该变换器中，输入电流在电感之间共享，因此变换器可以使用较低额定电流的电感来实现。因此，减小了变换器的尺寸和传导损耗，提高了效率。对所提出的变换器进行了分析，并给出了200W实验室样机的实验结果。

A non-isolated high step-up converter with low ripple input current and reduced voltage stress

In this paper a new non-isolated high step-up interleaved cascade converter is presented. In comparison with the conventional cascade boost converter, the proposed converter has a higher voltage gain, lower input current ripple and reduced voltage stress for the switches and diodes. Besides, unlike the conventional cascade boost converter, in the proposed converter the input current is shared between inductors and hence the converter can be implemented with lower current rated inductors. Thus, the converter size and conduction losses are reduced and the efficiency is increased. The proposed converter is analyzed and experimental results of a 200W laboratory prototype are presented.
