HI,
Please see attached.
I’m looking to use a photo-voltaic cell and 2 inductors to use light to wirelessly power an LED. I don’t want to use any other power source (battery, mains, etc.). The schematic shows a DC source (photo-voltaic cell) in parallel with a capacitor and an inductor. The second inductor would ideally be an inch or so away from the first, connected to a bridge rectifier, which provides DC current to an LED. Again, the important thing is to be wireless (2 inductors) and to be only powered by light. So, if I were to walk in a room and flip on a switch, the LED would come on. If I flip off the switch the LED turns off. The only confusion I have is on the photo-voltaic side. I’m not sure how to use the photo-voltaic cell to create a constant AC signal for the inductor. Help please.
