Resonant Mechanism for a Long-Distance Wireless Power Transfer Using Class E PA and GaN HEMT

Energies, 2023
This paper presents a study on long-distance wireless power transfer (WPT), which formulates the voltage gain in terms of the coupling coefficient between the power transmitting unit (PTU) and the power receiving unit (PRU) coils.

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Analysis and Implementation of High-Performance DC-DC Step-Up Converter for Multilevel Boost Structure

Frontiers in Energy Research, 2019
The conventional DC-DC converters such as SEPIC, boost converter, etc. produces large voltage ripples in multilevel converter systems. For that reason, in this paper, a new DC-DC converter topology is proposed, and the performance is analyzed.

Improvement on voltage gain for KY converter

IET Power Electronics, 2015
A novel step‐up converter, which combines a KY converter, which is named after the first capitals of two authors’ names: Hwu and Yau, a traditional synchronously rectified (SR) boost converter, and a coupled inductor with turns ratio, is presented in this study. In this converter, these two combined converters use the same switches.
