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.
@opor
same here too i dont have any test instruments, only ears and fingertips, it is a lot better in sound compared to the authors circuit. i have tested it in mid tops sound is clear. very nice

You only need a sound card for thd and imd measuremnts..even motherboard bundled ones have <0.01.

bridging ucd amplifier
Hi Manojtm
greetings having made ucd amp and playing it at 60 dc rails its working ok do you have any schematic BRIDGED ir2110 amp or schematic for this amp bridged can you help out
warm regards

hi bro thanks for the tips, anyway i will try to send it to a friend of mine sir irvyne jay, he had the test instruments to test it. i only know how to use dmm.

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 theorist😀3
Catch a working bridge😉

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🙄
Didn't find blue😱No..blue and yelow are lower..look here:
