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.
