Single phase power factor correction: a survey

TL;DR: A review of the most interesting solutions for single phase and low power applications is carried out in this article, where the major advantages and disadvantages are highlighted and the field of application is found.
Journal ArticleDOI

Review and Comparison of Step-Up Transformerless Topologies for Photovoltaic AC-Module Application

TL;DR: In this article, a comprehensive review of step-up single-phase non-isolated inverters suitable for ac-module applications is presented, where the selected solutions are designed and simulated complying with the benchmark obtaining passive and semiconductor components ratings.

A MHz-repetition-rate hard X-ray free-electron laser driven by a superconducting linear accelerator

W. Decking, +481 more
- 18 May 2020 - 
TL;DR: The European XFEL as discussed by the authors is a hard X-ray free-electron laser (FEL) based on a highelectron-energy superconducting linear accelerator, which allows for the acceleration of many electron bunches within one radio-frequency pulse of the accelerating voltage and, in turn, for the generation of a large number of hard Xray pulses.
Journal ArticleDOI

A Wireless Charging System Applying Phase-Shift and Amplitude Control to Maximize Efficiency and Extractable Power

TL;DR: In this paper, the authors present a method to maximize the efficiency and increase the amount of extractable power of a WPT system operating in non-resonant operation, which is based on actively modifying the equivalent secondary-side load impedance by controlling the phase shift of the active rectifier and its output voltage level.
Journal ArticleDOI

Impedance-Based Stability and Transient-Performance Assessment Applying Maximum Peak Criteria

TL;DR: In this article, the authors discuss the circle-like forbidden region occupying minimum area in the complex plane, defined by applying maximum peak criteria, which is well-known theory in control engineering.
