SUMMARY

The discussion centers on calculating the theoretical transfer efficiency of a wireless energy system, specifically referencing Andre Kurs's paper "Power transfer through strongly coupled resonances." The user, redhot2k4, seeks guidance on applying coupled mode theory to a system utilizing LC resonant circuits with raised capacitive plates. Michael suggests that the self-resonance of the coils may not significantly impact the applicability of Kurs's formula, as capacitance is inherently part of both self-resonant and non-self-resonant inductors.

PREREQUISITES
  • Understanding of coupled mode theory
  • Familiarity with LC resonant circuits
  • Knowledge of wireless energy transfer principles
  • Basic grasp of inductance and capacitance concepts
NEXT STEPS
  • Study Andre Kurs's paper "Power transfer through strongly coupled resonances"
  • Research the principles of LC resonant circuits and their applications
  • Explore the impact of coil design on energy transfer efficiency
  • Learn about the mathematical modeling of wireless energy systems
USEFUL FOR

Engineers, researchers, and students involved in wireless energy transfer systems, particularly those interested in optimizing transfer efficiency through theoretical calculations and practical applications.

Homework Statement


I have built a wireless system as described at the following site http://www.ar2r.50webs.com/wte/wte.html"

I would like to be able to apply some theory to it and calculate a theoretical value for the transfer efficiency over certain distances

Does anybody have any idea of the theory I would need to use??

The Attempt at a Solution



In a paper by Andre Kurs, "Power transfer through strongly coupled resonances" he derives a formula for transfer efficiency from coupled mode theory however it is complicated and the coils he uses are self resonant, where as mine have a raised capacitive plate making them an LC resonant circuit

Any help would be greatly appreciated

Cheers

redhot2k4,

Would it matter whether the coil was self-resonant or not? The self-resonant inductors still use capacitance, but it's part of the coil... I would think you could use the same formula.
