    EMC issue

    VE1BLL, the signals are likely single frequency (1x spectral peak) and the circuit linear. If it isn't, for a given input amplitude, one may adjust the RLC values, not ? If so - with no other disturbances present - the signal would produce neighter harmonics nor intermodulations. Nulling...

    EMC issue

    VE1BLL, thank you for the instructive overview on alternatives. I were looking only at the proposed design (concentric coils along a center line). So that brought fresh air already. "...have to reduce the signal enough to keep the amplitude in the linear region in subsequent active circuits...

    EMC issue

    VE1BLL, ok, there is a factor x1000 between the kHz and MHz signal wave length. Still the field produced by the sending power coil penetrates the receiving data coils ? Could you be a bit less enigmatic, please.

    EMC issue

    Hello everyone, with have a set of coils for inductive power and data transmission. These are arranged as two sets of concentric primary and secondary coils in front of each other. The coils differ in diameter and strand arrangement. The data signals operate in the MHz, the power signal in the...
