Looks like the IRS2453 circuit above does not operate at resonance frequency, it operates at a preset frequency but no information what KHz that is or how to set it?
Circuit above shows no RC circuit, no capacitors in parallel with the load coil. Everything I read says the capacitors are important it gives the work coil power to do its job. I was reading where someone built this circuit it says to add capacitors or circuit does not work.
These circuits are frustrating. I don't like building circuits that don't work. If I build this with parts laying all over the work bench its not hard to make changes, but if I build a nice circuit it is not easy to make changes.
