The objective of this manuscript is to analyze and design a new interleaved dc–dc buck‐type converter based on the conventional interleaved topologies. The proposed converter consists of small size filters, few component numbers, and low current and voltage ripple compared with interleaved dc–dc converter family. Furthermore, detailed comparisons are made concerning the operating mode, the component numbers, dc voltage gain, voltage stresses, output inductor current ripple, rated power, and efficiency. The presented converter might replace the conventional dc–dc step‐down voltage converter stage of poor power quality and low energy density, such as the one used in high power ac–dc battery chargers and dc sources, among others. Experimental results conducted on a 4.8‐kW laboratory prototype are presented to validate the theoretical study and prove the effectiveness of the proposed topology. The maximum efficiency level reaches 97.2% at rated power.

使用耦合电感器的四相交错式DC-DC降压转换器，用于大功率应用

本手稿的目的是分析和设计一种基于常规交错式拓扑的新型交错式dc-dc buck型转换器。与交错式dc-dc转换器系列相比，拟议的转换器包括小型滤波器，少量组件，低电流和电压纹波。此外，对工作模式，组件编号，直流电压增益，电压应力，输出电感器电流纹波，额定功率和效率进行了详细的比较。提出的转换器可能会替代电能质量差且能量密度低的常规DC-DC降压转换器，例如用于高功率AC-DC电池充电器和DC电源的转换器。实验结果进行了4。提出了8kW的实验室原型以验证理论研究并证明所提出拓扑的有效性。在额定功率下，最高效率达到97.2％。
