Summary: This article presents a fully soft-switched expandable high step-down dc-dc converter. The integration of synchronous buck and Cuk converters allows for a high step-down voltage conversion ratio and low component count. The splitting of the input voltage reduces the switches' conduction loss and the soft-switching operation of semiconductor devices mitigates switching losses and reverse recovery problems. The converter's efficiency is significantly improved by utilizing a switch for soft-switching operation and synchronous rectification. The converter also features a common ground between input and output and a continuous output current without additional current ripple cancellation methods. The proposed converter's operating principles and analysis are discussed, and the implemented prototype verifies its operation and performance.

Summary: With the increasing popularity of series resonant converters in grids and microgrids, the importance of a robust converter with fault-tolerant feature becomes paramount. This article analyzes the self-reliant characteristic of a series resonant converter for different fault conditions and proposes a post-fault correction method to maintain the continuity of operation and the rated output voltage. The method uses an FT capacitor and control parameter variation for single-switch and different combinations of two-switch faults.

Summary: This paper studies the addition of several voltage step-up cells on the primary and secondary sides of an isolated dc-dc SEPIC to increase its static gain and synthesize a family of converters. The study includes theoretical and comparative analyses, tables and curves with relevant information, and the identification of the use of coupled inductor or transformer based on the analysis of dc magnetizing current. The proposed topology and concept are validated through theoretical analysis and experimental results.

Summary: A new single-ended primary-inductor converter (SEPIC)-based step-up dc-dc converter is proposed, which integrates discontinuous-current quasi-Z-source (qZS) and switched-capacitor networks. The converter has low input current ripple, wide voltage gain range, and a constant potential difference between the grounds of its input and output ports, making it suitable for interface between fuel cells and DC-link buses in electric vehicles. Analysis for steady-state operations and a scaled-down prototype were conducted to validate the feasibility of the converter.

Summary: This paper presents a non-isolated coupled-inductor high step-down converter operating in discontinuous conduction mode, reducing switching losses and diode reverse recovery problem losses. A self-drive circuit is used to generate gate signals for the synchronous rectifier, recovering gate energy and reducing complexity. The topology involves only a single coupled inductor, decreasing size and cost of the converter.
