Hybrid Switched Inductor-Capacitor Network–Based High Step-Down Ratio DC-DC Converter for On-Board EV Charger Applications
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.
