New smallest case

I edited

yes 2x18650 series, I use 3 batts in my primary IH and it can heating over 30 times

I have a small version but the battery capacity is a big problem. It can only be used for heating several times

1 oven is sold in my country, build very ugly and working unstable :ko::ko: And this is my oven, still ugly but working very good :lol::lol:

compact with 2 light indicator

after heating, temperature of FET about 55*C and it cool down fast so I think when we heating again after 1-2 mins it OK ^^ I think you can DIY 1 heater like me and forget the module you buy on EBAY ^^

Thank for your advice, I'm check again, measuring direct input IH, the curent is 14A Temperature of transistors is under 60*C I think is not too high because we using IH with shot time.

I using step down from 24voltDC to 12volt DC. The ampe meter measuring DC ampe, 4x330nF 400V. I dont have oscillos. What you want see on osc ?

Made new one more compact :lol::lol:. I love making this :rofl: Fast click tips

Hi everybody, I make a new circuit and have some testing the position of the vap in heater. I want to know the position of the vap in your heater in any case, 1 or 2 and what the best case ? thank you for reading ^^ Case 1 the vap tip inside the coil. Case 2 the vap tip outside the coil.

My circuit using IRFZ44N and it working good

updgrade it using 1 hand like my prototype ^^

I think the issue is the quality of ZVS. You need to test the temperature of ZVS when it working. If anything on the board when heating you touch feeling too hot (about 70 *C) that is not good

I need to know your circuit. Take some detail picture

I thing 1 FET death. You can replace new 2 FET

click like this video is slow or fast, everybody ?

My first prototye, I thing it bad, heat up to slow.
