I´m trying to build an induction heater, I have builded four of them and only two worked, one of these blew up both IRFZ44N (first it was working fine). I think that my mistake it´s about the chokes, I´m using a chinese chokes extracted from another ZVS broken and I haven´t how to measure the inductance (I´m waiting a LM339N to make an "inductance meter" with arduino). My doubt it´s how can I know, which is the value and number of chokes that are necessary in my circuit. Thanks

  • \$\begingroup\$ Words are great, but pictures and diagrams are much more useful. If you can supply us with diagrams and/or schematics of what you have already tried then we can help point out errors in values, etc. Else we move on, as we do not like to guess about what we cannot see. \$\endgroup\$ – Sparky256 Jan 1 at 23:55
  • \$\begingroup\$ Be aware that you can get crappy hobby versions of most fancy types of meter on aliexpress for $10-20. It's not like using the real thing, but if you don't have an oscilloscope at all or you can't measure inductance at all, they are far far better than nothing. \$\endgroup\$ – K H Jan 2 at 0:56
  • \$\begingroup\$ I can't tell from the post what you actually want to find, or tell the induction heater apart from the circuit. Did you burn out the gate of the mosfet? Or did it die a heat death? \$\endgroup\$ – Voltage Spike Jan 3 at 17:10
  • \$\begingroup\$ The MOSFET (one of them) die in a heat death... \$\endgroup\$ – Doc_Physics Jan 6 at 0:14
