Hi,
Why do the designers of wireless power transmission circuits used to use high frequencies for transmitting the power wirelessly?
For instance the designer here in the bellow link uses more than 200 to 300KHz to sent the power wirelessly? If the higher freq is more efficient than the lower ones then what's the reason plz:
