UCD 25 watts to 1200 watts using 2 mosfets

[Vahrezyvalm]

Oops it is dual sided , I learnt the hard way dual sided boards are better than single sided also i strictly use smd . for the above reasons

yeah,its okay,I know that you prefer dual layer with smd parts than single,I had guessed it before.I'll use matrix board pcb.if you has completed and try it please review it here.

Hi Stewin,if your layout design has finished,please sharing it here.

Hi, what is the value of the output filter, please amplifier with IRS3000D?

My class D DC8000

hi robson irs900 works nicely but if you disconnect speaker or load while the amp is playing it fails

Try to add exactly here for output stage.

 

[kartino]

And this is secret recipe to prevent your amp from sudden fail, dead mosfet instantly. I believe it is also your nightmare.

 

[kartino]

The above two recipe will make your amp very rugged. Even you can play with supply up to 140Vdc supply and maybe more if you get proper mosfet. A lot of chance. Don't limit yourself

Hi is there anyone who can share PCB and all required files for ucd 25 watts to 1200 watts using 2 mosfets. I need to build a 200W @ 8ohm class D amplifier for a sub-woofer. Thanks in advance

Regards

hi katrino, thanks for the update .i will implement the modifications and post the results here

 

[kartino]

This is my Schematics D2KNeo and PCB picture. Just to give you idea, of maybe redraw from this picture. 2 sets mosfet Class D. I cannot give PDF of layout. You cannot just simply move this picture as some tracks are optimized to get very less capacitance hence as small as possible for small signal. Just give you idea.

Regards,
kartino

Hi Stewin,

Don't worry. It is very stable after. You can play switch on an off as much as you can without smoke, or you forget to put speaker and maybe speaker cable cut accidentaly.

For you are in indonesia, you can order PCB via tokopedia to Bie Tronik.
You can include also with complete parts.

Nice pcb!
Can you send brd. file?

 

[masood]

Sir.
Plz.send me also pcb in pdf form

 

[kartino]

As I told before. No PCB gerber or pdf.
One missing info, the cap GND need jumper to GND port as too small at the present PCB for trial. The other is just fine.

Hi kartino
can i create and test it?

Good day to all where can i buy a troidal transformer for my peavey GPS2600 power amp. thnx

 

[eeraudio]

My irs900d with 73vdc works fine midle volune but when push it a little the ofset voltage is geting high, it kick the protect circuit whats the probale problem? thnx

 

[stewin]

hi katrino post photos of your amp while playing . also videoz

Hello. Sorry for my bad english, I'm from another country. IRS 1500 series amplifiers are working or not? I want to collect the D-class amplifier 8 ohms 700 watts for the subwoofer. filter at the output of which the inductance?
