The State of Dynamic and Wireless In‐Motion Power Delivery to Grounded Mobile Robots

IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.
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 ...

Natural Soft‐Switching Extended Phase‐Shift Control of Dual Active Bridge for High‐Efficiency Battery Charging and Discharging

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper adopts a Neutral‐Point‐Clamped H‐bridge (NPC‐H) DAB topology to mitigate voltage stress on the input‐side switches. For both charging and discharging scenarios, a direct current control method is proposed using the output current as the primary control variable.

Energy Management of a Fuel Cell–Supercapacitor Hybrid System With Dedicated Charging Converter

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
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 ...
