Hi everyone,
I’m trying to find and hire someone with experience in electrical and electronics for my project. Full time, part time, or contractors are all fine with me.
The kind of work involved is as follows (only the green PCB board):
Can you be more specific with what exactly you’re looking for in terms of what needs to be done? I have plenty of experience, but this is a bit too vague.

Hi Doug,
The pictures you see above is the inside of a high performance induction burner. I’m trying to build a smart high performance induction burner. So I want to reverse engineer this and integrate it with a computer tablet.
The jobs need to done are:
-the schematics design
-a PCB layout (Gerber file) for pcb manufacturers.
-testings
If you are interested, I’m glad to do a call and discuss on this.
Why do you want to reverse engineer the whole thing? Can you only reverse engineer the control circuitry and make only that part controllable over WiFi or Bluetooth?

I have a different form factor. I need a layout that’s a bit more compact than this. I believe their design hasn’t been updated for 8 years. But their circuit topology and principles are still the best according to some research paper that I read. They use half bridge resonant with IGBTs.
The teardown’s original form:
The cooktop I’m trying to build:
Designing this is NOT going to be an easy task (read: very expensive and lots of billed design hours). The electronics is actually the easy part–thermal management is a PITA for something like this.
IGBTs are fine for consumer power (if you really wanted to be “high tech” you’d use GaN FETs) as you’re limited to roughly 1800W max (120VAC * 15 Amps roughly). However, it does mean that these things don’t generate anywhere near as much heat as they would in the EU or China–this is one of the reasons why induction devices aren’t so popular in the US–they only have about half the heating power.
You’d be better off finding something on Alibaba that does the “induction” part of the problem (IGBT’s are actually bog standard and there are lots of choices) so you can get on with the “design” part of the equation:
Good luck.

I agree with the above. That’s why I suggested to only focus on the control part.
It will be easier and you will get ur product out sooner.

Thanks for the thorough advice. I have reached out the manufacturer. They unfortunately don’t offer half bridge IGBTs products for 110V outlets. Also, I haven’t found other manufacturer offering that. So I guess maybe I still have to do the design. But I’m still negotiating with them.
I also agree. I see this is a faster route to the market. But what the manufacturer offers sometimes is just short of what I want.
I still need an electrical person if anyone could make an introduction. That would be greatly appreciated!
