hi there,
sorry if my post is out of forum,
yesterday, i got a cordless phone for repair, the hand set had no pin for charging(like electric toothbrushes)(cordless power charging), but there was a coil inside it(near 15number)as secondary and another coil in the hand set holder as primary,
and a circuit as oscillator of course,
it seems the circuit oscillates at 2.56MHz.
i tried to find any info or any related link or circuit in the net but it seems there is no thing or perhaps my kye words was not so good!
can anyone help me please?
any info or link or circuit,etc
P.s these kind of circuits can be made at very small sizes because they work at high freq range, and so their coils have a few nember of wires...
