Resonant Wireless Power Transfer Workshop

Wireless Power Workshop0.jpg

In this presentation we're going to use the $7 ZVS drivers made for induction heating to provide wireless power for LEDs in your fish tank, toy cars that are powered from under the track, charging your smart watch with a loop in the steering wheel of your car and another in your watch band (good coupling :) )...Etc.


First draft of slides so go easy on me...
