HELLO

Hi Kirubakaran
greetings before you attempt making d class amps get a proper core T157-2 OR SIMILAR MATERIAL 2 CORE irs 900 amp i feel very sensitive if proper core is not used try the irs 3000 pcb its working good
has ocp will save your mosfets detex audio has changed pcb layout with a reason DONT try IRS2092 till you have made a few dclass amps its cost in india is about400 rs
warm regards
andrew lebon DONT TRY OTHER CORES

RNS,please check

 

[andrewlebon]

pcb of irs 3000 is on post 2602 component placement same as irs 1500

Hi,

Which toroid is better for class D amps? Sendust core or iron power type 2?

Thanks

IRS3000D

RNS CHECK PLS.

hi i will make the amp i am interested for the one with irfp250 +/-80vlts switching at 250KHz

Hi stewin,

with limitter or without limitter which one you ask and PCB not compleated

REGARDS
MANOJ

without limiter but with overcurrent protection if possible . you can add totem pole so i can use 3 pairs irfp260n

One question..

Is it safe to use 200v Vds (like IRFP250) MOSFETs with +/-100v supplies in this circuit (the first 1250W into 4R one)..

I integrated the OCP in the bias regulator for IRS900

You just need to put a shunt resistor in the low side of IRS900 and cut the "SD to ground" track in IR2110 IC.

Then connect the "pad-sense" pin between the shunt resistor and lowside mosfet.
Connect the "pad-prot" to SD pin of IR2110.

The OCP is based on IRS2000.
LM311 outputs "low" if overcurrent is detected, then triggers the NE555 to output "high" to the SD pin of IR2110 for n seconds.

hello sir manoj,
is this schema available in pdf format??????

 

[exflaco]

Jlester good job ,thanks for sharing here....

 

[stewin]

hi all .andrewlebon and exflaco. guys can this ultrafast igbt IRG4PC50U be used in this circuit to give an output of 3kwts ?

 

[andrewlebon]

Hi Stewin
greetings no expert on SMPS but etd 49 would be small for 3kw
warm regards
andrew lebon

 

[pergo]

that's IGBT is too slow 😉 max 40kHz in hard switching

 

[manojtm]

Hi Stewin,

can you tell me the air gap of ETD49 and EE19. A=?? for 95V load

Regards
Manoj

Hi sweet,

I will give you the sprint layout file for AUD600 & Power AUD600

Regards
Manoj

 

[andrewlebon]

NO AIR GAP IN ETD49 its good smps
warm regards

[andrewlebon]

1.2KVA SMPS WITH IRS 3.5 k

Need to make higher power smps
