ZVS Induction heater 2000W 40A 50V

Looks impressive and well build
May I ask if you if you have tried using litz wire for heating coil instead of the copper tube? I have been working with a smaller 1000W ZVS drive and trying to optimize the electrical hysteresis by heating an iron pipe (high ferromagnetic material). Using a copper tube as heating coil the iron (Fe) heats faster than when using a litz wire. Theoretically it should be the other way around.

Lepel RF generator is something new for me, is it using vacuum tubes? Do you have schematic?

I am planing to build mains powered PLL induction heater. I am aiming on about 3kW power

Were you able to design the 3kW? I would be very interested in seeing it in action.

Hey thanks for sharing this! Im a beginner in Electronics and i wanted to know what should be the power rating of the resistors? I noticed in the order history, you shared on Drive, that the 1k and the 10K are 1/4W but no info on the other ones.

Do you have the Altium source files for you rev. 2 board with protection?

Hello,

Could you tell what is the gauge of the wire you've used to make the inductors? As I've seen there are 32w of 4-wire wick.
