Just got my hands on a complete induction look-top from my local repear shop and i was very surprised to find that there is now capacitor in the hot plate ether the coil is gust plugged straight into the pus-pull half bridge with now cap at all how the hell dose that work
Here's some pics of the small hot plate

An induction heater doesn't require a resonont circuit. All it needs to do is induce larger urrents in a work piece. Resonance is just an easy way to get that. Plus it alows zvs. Without a capacitor you get a lot of ringing and crazy spikes all over the place. Maybe they allowed for that?

well the guy in the repeir shop said that the slitest flucshuation in the mains voltage can destroy them

It makes sense if the circuit is mostly inductive. The circuit would have to be kept as flats Lena's possible.
