I have three of the same coil, i am planning on stacking the two for the receiving side. It will be less efficient and more bulky, but i think its better than manually making a coil as that could turn out more inefficient.

I have aimed at sending a signal at around 275kHz. It has an LC tank where C is 54nF. Receiver coil: ID - 20mm OD - 42mm It can talk to the charger through bluetooth using an onboard esp32. Turning on and off the transmitter is possible, but the recieving end has no sensing functionality as of...

Nothing should be visible externally, but there is a possibility to have the charging coil inside the receiving coil. They will be over a cm apart though.

It is for charging a battery connected to a custom external board. It does not need to be too efficient but should deliver some amount of power

I need a circuit that converts 5V DC to 5V AC and can supply 5W for a wireless charging coil. I am finding incredibly little information online Edit: It also needs to run at 275kHz, so a standard relaxation oscillator to my knowledge would not work
