Design and Optimisation for Hybrid Inductive and Capacitive Wireless Power Transfer System Considering Coupler Misalignment

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
The fishbone‐type capacitive coupler in the HWPT system can effectively restrict the flow path of eddy currents, thereby weakening the effect of the eddy current magnetic field. ABSTRACT The hybrid inductive and capacitive wireless power transfer (HWPT) system is confronted with the dual challenges of the eddy current effect brought by the integration ...

A Semi‐Quadratic Buck/Boost Converter With Dual Operating Modes and Continuous Input/Output Current for Renewable Energy

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
High‐gain DC‐DC converters play a vital role in photovoltaic conversion systems. Achieving high gain often requires operating at extremely high duty cycles, which can lead to increased costs, higher power losses, and reduced system performance. To address these challenges, this study proposes a non‐isolated semi‐quadratic DC‐DC converter, which is ...

The Misalignment Tolerance in Square and Hexagonal Matrix Capacitive Power Transfer Systems: A Comparative Study

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This work quantifies the misalignment tolerance in square and hexagonal matrix capacitive power transfer systems through a detailed comparison of the impact of 2D misalignment on the pi‐model capacitances for both configurations. The results demonstrate that the hexagonal structure reduces mutual coupling capacitance variation by up to 9.3%, depending ...

Comparative Analysis of Two, Four, and Six Plate Structures of Capacitive Power Transfer for Electric Vehicles

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Capacitive power transfer (CPT) is a new wireless transmission technique using an electric field instead of a magnetic field, and has merit in low EMI, weight reduction, and simple structure. However, traditional CPT systems have had difficulty with transmission efficiency and coupling stability, especially under misalignment conditions for high‐power ...

Understanding Drivers of Sustained Engagement in SMS‐Based Nutrition Programmes: A Realist Evaluation With an Equity Lens in Tanzania

Maternal &Child Nutrition, Volume 21, Issue 4, October 2025.
ABSTRACT Child undernutrition remains a global challenge, intricately linked to systemic inequities in access to maternal and child health and nutrition (MCHN) services. While SMS‐based behaviour change communication (BCC) offers a scalable strategy to address this challenge, its effectiveness is often undermined by low and inconsistent user engagement.
