  • Powerful yet simple induction heater

    Sorry Downunder35m for my late reply.Yeah I cheked my head and realized that those currents are... well overkill :) I think I will continue with your desing and go from there to learn if I need more power. Heh heh I tend to get a bit crazy when designing stuff, but who want's to denide the scientists with in!!I will absorb more info and continue. I really do appreciate you input on this and give you my thanks once again.

  • Powerful yet simple induction heater

    First of! Excelent tutorial/guide/explanation, ThanksI have couple of those ZVS ebay heaters (120W and 1000W version), but I want to make one that can fit to the container I have in mind. I'm going to use this as a car bolt heater.. Anyway, I'm thinking of using a welder inverter as a power supply. Do you think it will work? The idle voltage is around 70vdc, can't seem to find the ON LOAD voltage information, but the current is around 140A. I think the inverter would be ideal as I don't have to make a rectifier and also it will be wayyy lighter than welding transformer..I have many 500V, 46A, 0.24ohm, 200ns MOSFETs so these should at least handle the input voltage increase?How about the R1 and R2. How many wats are they?How thick the choke winding should be? Haven't got any idea how thi...see more »First of!

    Oh yes and of course I will need more than 46A current capacity from the fets if I want to run even close to 140A :)
