I want to use these drivers for an H bridge but havent figured how to properly connect them so that they work. Here is the part of the schematic that includes them: As this,when i put all of this on a test board it does not move a bit. The upper mosfets should switch at 50Hz and the bottom ones at 8MHz. The upper part of the H bridge ~350V This is part of an inverter. Thanks a lot for any advice.

I need some help in choosing the right wire size for a push-pull transformer that has 12v(min of 9 ,max of 18) input and 350v output. The Ae=76mm^2,and it is working at a switching freq of 100kHz.From the design i understand that the output is working at 200kHz. 175W input->150W output:so there are about 19.44 amperes at the input(worst case)and 0.428 amperes at output.

I want to build a step-up trafo that should have an input voltage of 12V and output of 350V.The power should be 175W in,150W out. How many coils,how thick should the wire be and other questions like this could your answers. The core is a ferrite core,ETD29 3C90 from ferroxcube,with a Ve=5460mm^3,Amin=71mm^2,Ae=76mm^2. I got some advice that Bmax should be around 0.2T(2000Gauss) and J=2.5A/mm^2. Where could i find formulas to resolve this design? Thank you for your tips.
