提出1种准Z源耦合电感低纹波DC-DC变换器，该变换器集成了准Z源网络、耦合电感和倍压单元。准Z源网络具有升压和无源钳位的功能，在变换器实现高增益的同时，开关管实现了无源钳位，回收了耦合电感的漏感能量。占空比在0~0.5范围时能够实现新能源发电所需的高增益、高效率和输入电流低纹波，避免了极端占空比带来的影响。然后对变换器进行了稳态分析、效率分析和实验验证，并和相似变换器的性能进行对比研究。最后，在实验室制作了200 W的实验样机，实验结果与理论分析基本一致。

Abstract

收起

A low-ripple DC-DC converter with quasi-Z-source coupled inductance is proposed, which integrates a quasi-Z-source network, a coupled inductor and voltage doubler cells. The quasi-Z-source network has functions of Boost voltage and passive clamp. While the converter achieves a high gain, the switching tube realizes passive clamp and recovers leakage energy from the coupled inductors. When the duty cycle is in the range of 0–0.5, the high gain, high efficiency and low ripple of input current required by new energy power generation can be achieved, avoiding the influence of an extreme duty cycle. The steady-state analysis, efficiency analysis and experimental verification for the converter were carried out, and its performance was compared with those of similar converters. A 200 W prototype was fabricated in a laboratory, and experimental results were basically consistent with the theoretical analysis.
