2 kwts discreet class d need help

Full-bridge at +\- 50V 4Ohm will result in 25A load current 100\4=25
we get for EI33 22uH , 25A , 5mm gap , 21turn
Copper the twice
So is not meaningful to apply it in a half-bridge.

Dimonis 1mm gaps will get core hot quickly, and what about coil size? proper coil size i needed to deliver enough current through it and decrease core being hot and stress too. This thing need to be experiment in real life will tell u everything

hi dimonis hope you can share the English version of your software...

Dimonis 1mm gaps will get core hot quickly,

At 12Amps no , at more than 15 - yes

This thing need to be experiment in real life will tell u everything

Don't agree , if normally calculated , the is no need to experiment in real life

hi dimonis hope you can share the English version of your software...

Sorry , it's not mine ,the is no translation yet.
The only translated is the SMPS transformer design tool , i'll post it tomorrow

[norazmi]

Dimonis, u can do simple translation by capture image and write into it

Yo Stewin, any update of ur amp? My ucd now current hunger and when do parallel mosfet need more capacitor banks or the power supply will clips amd drop hard. Im now Working on short circuit protection OCP and i`ll make proper test with 60va 24 0 24 vac first after success i`ll test with smps at high current.

hi all here are my updates i'm working on the pcb will post pictures

Hi Stewin
greetings NICE WORK
warm regards
