Why ZVS heaters use such thick coils, they often carry lots of amps but not THAT many?
Is it because of skin effect at higher frequencies?

IT IS A INDUCTANCE COIL MAKE OF COPPER, REQUIRES TO HAVE AS LESS AS RESISTANCE, THEREFORE, THICK COPPER COIL IS NEEDED.
THIS COIL IS THE ANTENNA FOR ITS RF POWER OUTPUT. IT SHOULD NOT GENERATE ANY HEAT WHILE NO EXTRA IRON METAL OBJECT IS PLACING ALONG THE COIL AREA. THIS TYPE HEATER USES EDDY CURRENT EFFECT TO CONVERT RF POWER INTO HEAT.
