It actually works!

Of course it works, several people built it before and published photos and videos. But now I did it on my own: a rather small induction heater.

In the first photo I ran it with only 12V and at about 2.5A, but this was enough to bring a small nail to red heat.

Some waveforms:
|
||
|
|
|
||
|
|
|
||
|
|
At the gate of one of the MOSFETs:

||

|

|
|
|
||
|
|
|
||
|
|
At the drain of one of the MOSFETs:
|
||
|

|

And finally across the capacitor:
