Hi /sci/, im working to reverse engineer this induction heater i got, and i think i have the right schematic (pic related).
Does this make sense? I find it particularly odd that the work coil doesn't seem to directly interact with the ground/negative terminal.
Those Schottky diodes are probably Schottky, they are model FR307. Feel free to assume that the values of all the components are reasonable.
Bump. Parallel thread in

Are the values of L1 and L2 different? If they are, it looks like they are meant to create two resonant circuits that have different resonant frequencies. It is probably meant to generate a higher frequency AC voltage for the load to use than just straight mains voltages.

A higher frequency would make sense seeing as it would result in larger eddy currents being induced in the material.
>>7983838
circuit doesn't make sense
where's the mosfets?
induction heating doesn't run on dc
A picture of L1, L2, and R1 and R2
The only components that are in the diagram are the ones that exist on the board. And it does, in fact, induction heat. But the specific wiring configuration im not 100% sure on

Whoops, here is pic related
>there arent any transistors
maybe hidden under the heat sink?
your diagram looks almost like ih.png

Hmm... well there IS this one bit, but im pretty sure they're just mounting brackets for the heat sink. Ill take a second look at it when i get home

under the toroids?
