First picture is the new circuit that I found online, I don't see how this can work?

Second picture is the circuit that works 35 amps, 735 watts.

I want to test this new circuit with no center tap on the 8T coil to see how it works or IF it works, compared to the circuit with a CT. It seems to me when each mosfet comes ON there are 2 ways for current to flow, through the 8T coil and around the 8T coil.

The amp meter shows 35 amps through the TESTED circuit with a 3/8" steel rod for a load it takes 7 seconds to turn red hot. I built a separate 10 vdc gate power supply. I have built new .1uh chokes. With no center tap the circuit will osc through all 8 turns of the 8T coil instead of 4 turns of the coil. Mosfets in both circuits are P55NF06L.

I want to do away with the CT so the coil can be wound with copper tubing and be water cooled.
