Description

This research introduces the behavior of Magnetorheological (MR) material as a core for Wireless Power Transfer (WPT) and Dynamic Wireless Power Transfer (DWPT) systems. MR fluids are flexible and easily fabricable material, although they offer a lower magnetic permeability compared to conventional Ferrite cores. The main objective of this research is to investigate the potential of MR fluid as a core for static and dynamic WPT system if it improves transfer efficiency, specially under misalignment and movement. MR fluids, known for their ability to rapidly change their rheological properties in response to magnetic fields, support the power transmission between transmitter and receiver coils, a critical factor in the efficiency of WPT systems. The research will involve using two prototypes, one for static WPT and one for a dynamic WPT system that can work with different cores like Air, ferrite, flex-ferrite, and MR fluid. These materials are used as a core in this experiment to compare their effectiveness in the system. Misalignment is inevitable in dynamic WPT (DWPT) and MR fluid has potential to perform better in this condition as a core as it has adaptable rheological properties, like viscosity, when exposed to a magnetic field. The study will evaluate the performance of WPT systems integrated with MR fluid under various positions including different misalignment percentages.
