+40V 0v -40v / 10A SMPS For Power Amplifier

[Andrew Lebon]

Hi Deepone
greetinks thanks for reply any idea what is value of preset and transistor numbers i want to try everything
warm regards

[DeepOne]

Greeting.
Certainly you can sure themselves but such scheme probably blast. ir2153 switching off it is necessary to do quickly and once.

Hi Andrew Lebon.

can i use igbts in my smps

yes. of course.

trying to make pcb for your wonderful smps

this already your wonderful smps )).

Hi Deepone
greetings can i remove all 4 IRFP460 AND REPLACE WITH IGBT IRG4PF50W are they ok to use i use freewheeling diodes
warm regards
andrew

 

[DeepOne]

can i remove all 4 IRFP460 AND REPLACE WITH IGBT IRG4PF50W

yes, you can ). One IRG4PF50W instead of two IRFP460.

ok to use i use freewheeling diodes

yes, they are ok. Or possible use IGBT with "D" index, like IRG4PC50UD, IRG4PF50WD.

Deepone And Andrew Many Thanx i'm about to finish and test

Deepone If i use IGBT with build in diode do i still need to put those 1.5ke440 's?

what is the oscillation freq of 2153 using 3.3k and 4700pf on pin 3 and 4

i use 3.3k and 4700pf main Core primary inductance 2.5mh(core T50,ee55,ETD59) is this correct sir Deepone?

 

[DeepOne]

Hi, Irvynejay.

do i still need to put those 1.5ke440 's?

If used 900V IGBT like IRG4PF50W that it is not necessary (but 900V IGBT will 30% more heat then 600V IGBT).
In general for half-bridge converter even with 600V keys these TVS is not obligatory components.

what is the oscillation freq of 2153 using 3.3k and 4700pf

As judged by datasheet frequency must be around 42 kHz.

Core primary inductance 2.5mh(core T50,ee55,ETD59) is this correct

I think for half-bridge topology primary inductance must be in 700 - 1000 uH interval. 2,5mH more suits for full bridge.

Hello Irvynejay
greetings NICE to see you make this smps
warm regards
andrew lebon

 

[irvynejay]

Thanx Andrew

Sir Deepone can you pls give details on what core to use and wire use for Current Transformer

Can this C T be use PE-51687

Hi Andrew Lebon,
I also want to make an smps of 2KW rating , so please specify which circuit did you use.

 

[Andrew Lebon]

post#14 and post#48 used to make smps
Hi Picgak
greetings combination of both above mentioned post used to make smps FOR totem trs use BD139 BD140
WARM REGARDS

Hi Deepone
greetings can this ocp be used for ir 2153 smps using current sensing trafo 1:100 turn ratio

Hi Andrew
For my opinion you can also use a low value resistor to sense current through the primary of your transformer and then limit it as well .

[picgak]

Andrew Lebon ,
From your pcb I think you have removed the triac part of the schematic and used a relay . Is it timer operated or according to the charge on the input cap
regards ani

 

[irvynejay]

@Picgak triac sofstart is replace with relay type softstart

 

[Andrew Lebon]

softstart used from this circuit

 

[DeepOne]

I have done audio amplifier (based on LME49830) with such power source too. Quite well, sound loud and clean.

hello deepone sir

Deepone sir Many Many Thanx i'm about to finish and test this smps
