What is this topology? Not is half-bridge. 300 volts are applied to the primary, I'm uncertain about the ratio of turns between primary and secondary. In one cycle it applies 300V and other it resets the transformer?

I mounted the above schema and works.
The polarity of the gate driver is the opposite of Layout1. It is as described in scheme 2 handmade.
Ran 44KHz and I will have to increase the number of turns of the transformer because my saturated and heated. I used 19 turns on a toroid with 1.95 cm2 of Ae, which would give 2300g. I will increase to 30 turns and stay in 1500G.
It really is half-bridge, I was confused because one leg missing capacitor voltage divider (between transformer and negative), but the voltage ratio is like a voltage divider. I used 11 +11 turns on the secondary and got 85V +85 V
