My class D amp

[de Ocampo]

My AUD600 Rev3.0 is suitable for any type of filter core like T106-2,ETD,EE & EI core with gap and supply voltage range will support like +/-35V to +/-85V and IRFP250N will support fsw up to @500KHz range with cool.my only problem was HF little low (using ETD,EE,EI with gap)compare to LOW and MID,but it is satisfactory.I am not started the PCB yet.

Hi Manoj,

This sounds very promising...guess I'll have to wait for rev. 3.0 then, but please let us know if it will be shared for DIY'ers in the forum.

Thank You!

Hi ALL,

My AUD600 Rev 1.1 change to Rev 3.0
First test fsw @460KHz with IRFP250 MOSFET run cool with Mid Volume temp 50 deg. with full drive @ 4 Ohms load.

MANOJ

Manoj Sir,
Pictures of your Amp shows that your work is very neat and clean.
Great Work Sir !!!

Nice work Manoj..

what is the main difference with your prevision designs ?
if it's possible , please give schematic to me. i'm working lots of month on class-d , still don't find a reliable design to improve and pcb designing.

Congratulations m friend
nice work

Hi Manoj,
use accurate LCR meter to measure the value of your inductor. maybe your ee type filters don't have enough inductance to reach a good cut-off freq. also as i calculated before , in lower loads , we lost some higher frequency and we should increase cut-off freq.

Hi IR,

Thanks. I changed cut-off freq. settings ; add a 474/400v capacitor now HF is good.

MANOJ

Manoj,

for best result @4ohm , use 18~20uH + 470nF , the cut-off freq should be higher than 50KHz. but this values are not very good for 8 Ohm loads.

Regards

 

[manojtm]

Hi IR,

Thanks.but when i increase the capacitor value HF is good why???

my inductor is @46uH capacitor 1uF then i add one 0.47uF now total capacitor value is @1.5uF

did you got my mail?

Hi all,

anyone have CAMCO Vortex 6 amp schematic

i got one for repairing and i don't have schematic.SORRY FOR THIS,its not a class d it is a class H but it had a power full SMPS(60A). anyone have pls share

hi manoj i found this fet irfb23n20. will it work comfortably with aud 600 or ir900,ir1k5 with +/-90vlts at 2 ohms?

hi manoj i found this fet irfb23n20. will it work comfortably with aud 600 or ir900,ir1k5 with +/-90vlts at 2 ohms?

Hi stewin,

it will not support 2 ohms @ 90V supply

Could you please post the schematic of AUD1000C,

Hi sayelend

i don't have shema for this .it was my old design with carrier based class d amp +/-90v supply
