TL;DR: In this paper, the importance of grid-connected PV system regarding the intermittent nature of renewable generation, and the characterization of PV generation with regard to grid code compliance is investigated and emphasized.

TL;DR: In this paper, the authors assess different MPPT techniques, provide background knowledge, implementation topology, grid interconnection of PV and solar microinverter requirements presented in the literature, doing depth comparisons between them with a brief discussion.

TL;DR: In this article, the authors present the state-of-the-art technical progress and research bottlenecks in wireless power transfer (WPT) development and applications in the transportation sector, and characterize the demonstrations of real-world deployment of WPT EV systems.

TL;DR: A sensorless three-level neutral-point-clamped inverter-fed induction motor drive is proposed and Fuzzy logic control and the speed-adaptive flux observer are introduced to enhance the performance of the system.

TL;DR: In this article, a two-coil structure with different resonant frequencies of the sending and receiving loops is modeled and analyzed, and the efficiency of a particular load is greatly influenced by the driving frequency.
