Hi,

For school I have to make a popcorn machine, I would like to use some kind of induction. I used this scheme, R1 and R2 are 240 ohm 0.6 W resistors, D1 and D2 are two Schottky diodes, T1 and T2 are 100V, 35A MOSFETs, C1 are two 330nF polypropylene capacitors, L2 is used as a choke and L1 is the coil in which I would like to put a metal cup.

I made this circuit but I couldn't get it to work.
Problems: - The MOSFETs got too hot.
- In only one of the two MOSETs was flowing a current.
- On both ends of C1 was the same voltage.

I hope someone can help me.
Thank you for reading

 

Here is one that works.

If you are using a metal cup in order to heat non inductive material, you may not get an even enough distribution of heat.
