摘要

一般来说，传统的DC-DC Cuk变换器在连续导通模式下工作时，会产生很高的输入电流纹波，并向电源注入不需要的谐波。因此，利用交错DC-DC Cuk变换器来减轻输入电流纹波。考虑到效率的重要性，本文提出了一种在结构上由单个辅助开关完成的全软开关交错DC-DC变换器。简单的控制电路仍然是PWM。对该变换器进行了分析和仿真。结果证实了稳态条件下的理论分析。

Analysis and Design of an Interleaved DC-DC Cuk Converter with High Efficiency

Generally, the operation of conventional DC-DC Cuk converter set on continuous conduction mode creates a high input current ripple and injects undesirable harmonics to the source. As a result, the interleaved DC-DC Cuk converter is utilized to mitigate the input current ripple. Since, high efficiency is important, in this paper, fully soft switched interleaved DC-DC converter is proposed which is done by a single auxiliary switch in its structure. The simple control circuit remains PWM. The converter is analyzed and simulated. The results approve the theoretical analysis at steady state condition.
