Abstract

The step-down DC-DC converter plays a vital role in transformer-less grid-connected on-board EV charging systems, enabling the reduction of voltage to desired levels. This study introduces a novel Hybrid Switched Inductor-Capacitor Network (HSICN)–based high step-down ratio DC-DC converter for on-board EV charger applications. Compared to recent converter designs, the proposed HSICN achieves an impressive step-down ratio while minimizing voltage stress on the switch, making it particularly suitable for high-power applications. Additionally, by distributing the output current between both inductors, the overall volume of magnetic components is reduced, leading to decreased conduction losses. Furthermore, this approach lowers the ripple current in the inductor, contributing to a reduction in the size of passive components. The operational principles of the proposed HSICN, alongside steady-state analysis, are thoroughly discussed in this study. Moreover, a comprehensive comparative assessment of the proposed converter's performance is provided. To validate its effectiveness, a 500-W experimental prototype was constructed and analyzed, demonstrating peak experimental efficiency of 95.8% at 350 W.

基于混合开关电感-电容网络的车载充电器高降压比DC-DC变换器

降压DC-DC变换器在无变压器并网的车载电动汽车充电系统中起着至关重要的作用，可以将电压降低到所需的水平。本文介绍了一种新型的基于混合开关电感-电容网络（HSICN）的高降压比DC-DC变换器，用于车载电动汽车充电器。与最近的转换器设计相比，提出的HSICN实现了令人印象深刻的降压比，同时最大限度地减少了开关上的电压应力，使其特别适合高功率应用。此外，通过在两个电感之间分配输出电流，磁性元件的总体体积减小，从而降低了传导损耗。此外，这种方法降低了电感中的纹波电流，有助于减小无源元件的尺寸。本研究深入讨论了HSICN的工作原理以及稳态分析。此外，还对所提出的变换器的性能进行了全面的比较评估。为了验证其有效性，构建了一个500-W的实验样机并进行了分析，在350 W时实验效率达到95.8%。
