The State of Dynamic and Wireless In‐Motion Power Delivery to Grounded Mobile Robots
ABSTRACT This work reviews efforts to develop systems for in‐motion wireless power delivery, that is, the transmission of energy to moving receivers (RX) through untethered interaction. The application in focus is supplying small‐to‐medium‐sized grounded mobile robots, but the insights extend beyond this context and the review serves as a platform for ...

Energy Management of a Fuel Cell–Supercapacitor Hybrid System With Dedicated Charging Converter
This paper proposes a coordinated energy management system (EMS) for a fuel cell–supercapacitor hybrid system interfaced through three isolated dual active bridge (DAB) converters. The proposed approach enhances system efficiency by reducing the number of power conversion stages and improving power flow coordination between the fuel cell and ...

Tegangan tinggi tidak hanya digunakan untuk keperluan transmisi, tetapi juga untuk penelitian di laboratorium. Pada umumnya, tegangan tinggi dibangkitkan menggunakan pembangkit tegangan tinggi konvensional yang berukuran besar. Oleh karena itu, diperlukan rangkaian yang lebih sederhana untuk membangkitkan tegangan tinggi, misalnya menggunakan konverter
