The 30N60A4D looks like a very good IGBT for SMPS use.

http://www.fairchildsemi.com/ds/HG/HGTG30N60A4D.pdf

> 100KHZ operation at 390VDC 30A = 11,700W

An ETD-49 core can give 3KW at 80 KHZ.

wow very amazing igbts

do you have a link of a former which can produce about 8kwts at 100khz

 

[wally7856]

An ETD-59 core can give almost 9KW at 100 KHZ.

Many mfg make this core.

hmmm, 9kW? at 100khz? I am not sure if ETD59 will give more than 4KW (safe) at 100KHZ.

FYI, it will hit 100C under full load for 15 minutes, for music use it will. i saw LECO in other thread got around 5KW from that core, but for short periods.

you made any SMPS wally ?

 

[wally7856]

Corvett, that 8KW is the maximum theoretical power from Pressmans SMPS book. I did not say you could actually wind it. You would have to use foil to get the most power from a core. But for music power you only have to be about 1/3 continuous power so 3KW will get you 9KW music power.

hi guys, i have these cores i think they're E65/62 cores can they work with a IGBT30n60d to produce over 5kw power? I found them in an old ups as inductors.
please help.

 

[MicrosiM]

Stewin,

You will get 5KW from EE65 core, I assume that you have the bobbin for this core also.

One way of success is litz wire in order to get high power, also core/IGBTs is part of the success, beside the drive circuit.

Good luck

oops i dont have the bobin but i am planning to use ply wood 2mm to make bobin.

do i need to make 1mm gap??

hi Stewin ,find here ETD59 PC40 material , can order small qty and price negotiable

Smps help

Hi Microsim
greetings well i built my first smps using this schematic and it WORKED first time on
want to increase power of this smps to about 2kw ihave used ETD 49 core these are the winding details

PRI WINDING 4 STRANDS OF 22 SWG TWISTED TOGETHER
SEC WINDING 5 STRANDS OF 22 SWG twisted together
MOSFET used IRF460

can IGBT IXCH32N60B be used instead of irf460 and ETD59 core in place of ETD49 and litz wire would these help in increasing power to 2kw this schematic works PERFECTLY just want little more power
from this schematic is it possible hoping you can help me SMPS not my cup of tea but this smps made me change my mind now trying to learn more about smps
warm regards
michelle

 

[wally7856]

2kw, 5kw, 8kw. What is everyone doing with these high power smps power supplies. I have a 200w stereo and it will blow the doors off of the house.

 

[michelle]

smps supply 1200 watts revised layout

Hi Microsim
greetings no reply to post 270 well detex audio sell these kits but what round core is being used in these smps hoping you can share your thoughts
warm regards
michelle!!!:

pic of round core used 5KW SMPS

Hi Microsim
greetings pic of round core used any idea what core and core material used
warm regards

Hi Michelle.


I really dont know the core material, but 3F3 or 3C90 should be fine.

Regarding your question of getting 2KW, you will need ETD-59, and 1.5mm Litz wire (minimum)

See Leco SMPS, and a GOOD driving circuit, and High current IGBT like 30N60A4d

Hope that helps

hi stewin

i have etd59 core with bobbin and hgtg30n60a4d ,brige rbv5006
what do you think ????

hi all friend,

have refrence for make SMPS with this part ?

a 2KW SMPS cab be easily made with that core and those robust IGBTs

 

[renotrend]

thanks Microsim,

can i get for 3kw or more with this part (sg3525,driver ir2110,igbt 30n60a4d,core etd59 material pc40,brige recitifier input rbv5006,enamail chopper wire 0.15mm x 200 strands) ??

3KW wont be an easy mission indeed, you have to start with 1KW, then raise the load slowly until you make sure that your SMPS is stable

And yes, yo can use 0.1x200, because i am not sure if 0.15x200 will fit when you wind it

Guys, im getting some problems whit this smsp, i build the transforme to get +-40v, but when i put a 47ohm resistor as load, the voltaje drops to +-30v, its this normal? i mean its only 1amp and drops 10v?

Any advice?

I am not sure about the exact reason for this, but if you answer below questions it may help me figure out.

1- Transformer you are using
2- Wire you are using
