@stewin , opor
hi guys here is my new bridge class d
What material is for the inductors ?
If it's a pure bridge - better wind both on one core.
That is the blue material of the toroids?on going project hope it works like gerry made thax sir gerry
Never seen before.
Hi All
This is My Final circuit with Over Temp.,Over Current,Auto Limiter,CLIP and DC Protect with Delayed ON.
I designed a PCB without Auto limiter,CLIP & DC Protect
It can give an OUTPUT 1,875Watt @4Ohm Load (3xIRFP250)
The L3 coil\inductor will simply melt based on that core

75V*75V /2/4Ohm =703Watt
Hi
greetings please can any one help to see if this schematic is correct for
bridging ucd amp as i am new to class d any help greatly appreciated
warm regards

Hi Andrew !
The schematic is relatively correct , I know the author , he's just an amatuer theorist3

ultra low .
How low?
The lowest that i know is "the red core" - permeability = 10

No..blue and yelow are lower..look here:
Toroids - Micro Metals / Iron Powder
Red is just more famous..i also used red because i had no space for others since more turns were needed for the same inductance.

It is an ultra low permeabily iron powder toroid.
Sorry , I got it - material №28 permeability = 22 , not so low аs though
