ZVS drivers like this are very simple and we'll documented, however I'd have trouble building one at that price.
They normally run around 60kHz - 120kHz, but it is a tuned circuit and depends on the inductance of the coil and it's leads plus the caps... The loading presented by the workpiece will also lower the frequency from the predicted value....
Just Google "zvs induction heater"... Or " royer induction heater"
NOTE: The capacitors on these tend to heat up A LOT due to internal losses - you should allow decent cooling if used continuously for more than a minute or so... The 4HV forum (of which I was an active member for many years) has a large amount of DIY induction heaters - the most popular was Marko's - see https://markobakula.wordpress.com/power-...on-heater/...
