TL;DR: A grid-connected wind energy conversion system (WECS) based on a permanent magnet synchronous generator (PMSG) operating with variable speed is presented, with the advantages of reduced conduction losses, simplified drive circuitry for the active switches, and high input power factor without the need to use multipliers in the control system.

TL;DR: In this article, a new three-port soft switching dc-dc converter topology based on the bidirectional version of the three-state switching cell is presented, which is feasible to interconnect battery bank with a dc link and photovoltaic panels.

TL;DR: This paper covers the application of a Dual-Active-Bridge DC-DC Converter in Vehicle-to-Grid (V2G) technology for DC Microgrids to achieve soft-switching in the whole operating range independently of the electric vehicle's battery state of charge while also ensuring stability of the Microgrid voltage port regardless of load or generation conditions.

TL;DR: The three-phase single-stage bidirectional ac-dc converter with high frequency isolation as a multiport power converter is proposed, suitable for the new concept of distributed generation, or smart-grids, interconnecting various sources and loads, controlling the power flow between them, with only one converter.

TL;DR: In this paper, an ac-dc bidirectional power converter topology consisting of an arrangement of full-bridge converters based on the three-state switching cell using a medium-frequency isolation transformer is proposed.
