Determine resonance point of the work coil

[gpatel]

Hi all,

I am a newbie and trying to build an induction melter myself. I want assistance in figuring out on how to get the resonance point or frequency of the Work coil online (During melting) as the load (metal to be melted will vary in terms of quantity).

Any circuit reference will be very helpful.

Many Thanks.

Use a phase locked loop.
