hi all!
Sorry for my English.
This is my first post in this forum, I'm also interested to make this SMPS project, please help to avoid future missteps, and therefore there are some questions that are still confusing me, it is:
1. If I do not find the right core, what alternative instead?. I have a core with size (/ - L * H * W) 49 * 27 * 17mm, what can be used?
2. I have two sizes of wire, 0.1mm and 0.4mm, which is suitable for the core?
3. If they fit or can be used, how the turn and strand should I make to the primary side and secondary side?, In this case the target is a symmetrical output +-75V /and +-50V.
4. What transformers are used to supply the SG and IR?, Could use a non-sealed transformer or from the main transformer? and why?
5. Can someone explain about the details Current transformer? (About cores are used, the wire size, number of turns, the jumper through current transformers, etc.).
6. In PWM circuit there are two trimmer (R12 & R13) and there is another one in the protected module (R5), what is its function?, And how to set it? ...
7. What is the total value of micro (u) capacitor (min) for each output rails?
8. What is the minimum value of amperes at Relay?
9. What kind of load used to test this project?, Maybe a lightbulb? Minimum or maximum number of Watt or the Ohm?
10. What about efficiency, the normal temperature of the FETs with or without a load, and can i see the complete scheme of this project as a reference source?
Thank you.:UP:

Hello sir microsim
My voltage drop problem was solved,the capaciter 1uf 400volt was defective. now i get full volt of +/- 50.
I replaced the mosfet to IGBT GRPC 50U ,the IGBT gets warm with out the output dc load . circuit is 1kv smps based on
microsim designed ludo,half bridge.
can i use the same design to increase the smps wattage to 5kvusing IGBT
can i use transformer etd59 instead of etd49 to increase the wattage
i dont know the primary and secondry winding
so please tell me the winding detial
can this 1kv smps be made regulated if yes then send me the modification schematic
thank you

Please check your Dead Time settings.

You can increase the power to 5KW if you use ETD59, and 75A IGBTs, LITz wire, and at least 125KHz.
can i use transformer etd59 instead of etd49 to increase the wattage
Yes you can
i dont know the primary and secondry winding
I need to know your secondary voltage to give you details of windings..
so please tell me the winding detial

Hello sir microsim
I Need windng detial of etd 59 my voltage is +/- 80v 15amp & +/-160,15amp .
this is my first smps of (high amp) so pls tell me how to adjust dead time and frequancy.
I use copper wire off 1mm for primary & secondry winding off ur design based on microsim 1kv
useing 2110 & sg3525 and etd 49 , I used igbt instead of fet the supply is +/-50volt,iwant to know
how much amp of +/-50volt will give &how much wattage will it go to maximam.
can this circuit be regulated,because,i want to know wheather it works from 180 to 230 volt ac if yes plse give
me the modification of schematic.
thank you

Hi michelle!
I'm also building a circuit pulse power supply circuit according to this principle. but now I have a problem is only 30kHz oscillator frequency. Can you tell me how to increase the frequency of oscillation.
This is my pcb.
Thanks!

last beta design no tested!
Hi all.
I have decided to definitely abandon smps dev.
i no have time and money for this, but i share my last design.
it's regulated smps, short circuit protected and over-voltage shutdown.
work with a GDT to provide isolation of primary side.
WARNING! This smps is not tested, i never made the pcb, only the drawing and simulation.
I post the eagles files. i hope this help people to make SMPS
View attachment smps 3525 GDT beta v4.00 no tested.zip
I do no provide any support for this smps, i no have the time and it's never tested in real life.
Bye

Hi to all of you. My name is Anton from Bosnia and Herzegovina.
I hava plan to build this SMPS declared like 1kW, but I need more power. I need at lest 2,5kW SMPS for my H-Class amp APEX H900 and that mean I need four secondaries on transformer and thats OK. I am wondering can I increase the power of SMPS with using larger transformer core like E55 and replacing IRF460 with IGBTs IRG4PC50U as well???
QSC PLX3402 SMPS uses them and I want to make something like this. Also that QSC SMPS uses IR2110, SG3525 and E55 core like this one.
Thank you

Hi Micro, I have a question, the duty cycle always should work on 50% for not regulated smps ? whats happen if my SG not give me more than 47% DT ?
