Wireless Power Transfer: Using Inductive Coupling for Battery Charger Applications Rafael Camarillo Daniel Costinett University of Tennessee College of Engineering Motivation: Medical Applications Heart Monitors Pace Makers Nerve Stimulator Automotive Applications Vehicle charging applications Dynamic charging Consumer Electronics Cell phone, Tablet charging Minimize Power Components Objectives: Design a system that will charge, a stand in AA or AAA battery using Inductive Coupling. Applying circuit techniques and analysis to correctly model systems in a Wireless Power Transfer application. Identify problems and take intermediate steps in resolving. Constraints: Transmitter and Receiver distance Battery must fit in standard AA or AAA holders Coil must be able to supply enough current for circuit and battery Results and Conclusions: Battery Charger System Troubleshooting: Current limitations Objects interacting with the coil Experimental and Simulation Differences Experimental Simulation Differences To minimize error in the simulation we can model each component according to the data sheet. Values taken from the datasheet. Current Limiting Future work: Finish Troubleshooting, Correct Modeling, Power Transferred We can identify current flow using the thermal camera helping in identifying problems. SPONSORS:
