WIRELESSCHARGINGSYSTEMDESIGNWITH SOLAR PHOTOVOLTAIC INTERFACE TOWARD BIO MEDICALDEVICES

Abstract
The adoption of wireless charging for bio medical is on the rise, promisingenhanceduserconvenience.Concurrently,thereisapressing need for increased integration of renewable energy into the medical sector to mitigate greenhouse gas emissions. However, wireless charging systems face challenges such as power transfer fluctuations under load and variations in coupling coefficients. This research introduces a novel solution: a Photovoltaic (PV)- integrated hybrid-compensated wireless charging system tailored for bio medical applications. The study addresses critical hurdles in achievingoptimalefficiencyandpowerdeliverywhileaccommodating significant misalignments inherent inWireless Power Transfer (WPT) systems,particularlybeneficialformedicaldevicecharging.Compared to conventional compensation WPT systems, the proposed hybrid compensation approach significantly enhances transfer efficiency and reduces system current stress. ThepaperproposestheutilizationofS-LCC/SP-compensatedconstant current(CC)andconstantvoltage(CV)systemforPV-integratedstatic WPT systems. Experimental validation of the proposed system is conducted on a 3.3-kW laboratory-scale prototype. The findings demonstrate consistent power transfer across a 100–200 mm air gap, maintaining an efficiency of 91.3%. These results confirm the effectiveness of the proposed system in real-world applications.
