Wireless Power Transfer Using Inductive Coupling for Battery

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 • We can identify current flow using thermal camera helping in identifying problems. SPONSORS: Future work: Finish Troubleshooting, Correct Modeling, Power Transferred
