I found this induction heater circuit on YouTube. There are several videos of people that have built this. One person used original parts. One person used a 12 volt regulator to reduce the voltage on the left 15 volt terminal. One person used 12 turn coil did not work well. One person used a 7 turn coil it work ok. One video is techinal data only it claims this circuit is only 100 watts. The Mosfets are rated 100v 35a that = 3500 watts each. Mosfets appear to be in push pull not sure how many watts this circuit is? Technical data says the choke is current limiting for the 9 turn choke if it is sized correctly it should be 15v 35a = 525 watts on each Mosfet. I think the voltage can be increased to 50v 30a = 1500 watts per Mosfet. That will be full load on my 1500 watt transformer. Can I put 50v on both terminals marked 15v? The frequency of the LC circuit is 225KHz.
