TL;DR: In this article, a contactless charging system for an electric vehicle (EV) battery is proposed, which consists of three parts: 1) a high-frequency power supply from a full-bridge inverter with frequency modulation; 2) a loosely coupled transformer that utilizes series resonant capacitors for both the primary and secondary windings; and 3) a rectification output circuit that uses a fullbridge diode rectifier.

TL;DR: In this article, the authors proposed a novel MOSFET-based phase leg configuration to minimize the failure risk from body diode reverse recovery, increased conduction losses due to more devices, or low magnetics utilization.

TL;DR: The proposed converter is designed as a series resonant converter with nominal-input voltage and operates under two additional modes: a boost converter with low- input voltage and a buck converter with high-input Voltage.

TL;DR: In this article, the effect of coupling coefficient deviation to compensation network efficiency is analyzed, and design considerations to reduce gap and misalignment effects for the inductive power transfer (IPT) system are proposed.

TL;DR: In this paper, a non-isolated, high boost ratio dc-dc converter with the application for photovoltaic (PV) modules is presented, which utilizes a hybrid transformer to incorporate the resonant operation mode into a traditional high-boost ratio active-clamp coupled-inductor pulse-width-modulation dc-DC converter, achieving zero-voltage switching (ZVS) turn-on of active switches and zero-current-switching turn-off of diodes.
