Wireless electricity???

rohitrangwani over 12 years ago

I am designing a circuit for transmitting electricity using resonating coils with resonance freqency in range of 20-50Hz with Sorce volage of 20 Vpp.

Does anybody knows something regarding maximizing power and distance of transmission for it??

Have you researched this topic via Google and Wikipedia ?

If not - then do, if you have then where are you stuck ?

No one can help you unless you define the problem better.
What are the constraints in terms of size and cost ?
How much power do you want to transfer ?
What level of efficiency is acceptable ?
What distance are you hoping to achieve ?
Based on your researches what is the baseline performance that you want to improve upon.

I tested the range of Qi-Compliant eval board about a year ago. Efficiency dropped off rapidly after 4mm, and I could get nothing beyond 6mm. Let me know if you get more!
