1kW smps project (based on MicrosiM design)

Dear Microsim, what should be the ideal value for Ho (IR2110) capacitor ??

My latest work .. in progress..

Dear Microsim, what should be the ideal value for Ho (IR2110) capacitor ??

I am not sure witch capacitor exactly, please provide more info.

Looks GOOD! hope to see results soon!

I have ordered a few PCBs of my version of the SMPS design. Two sided in PCB green circa 14x12cm.
Here is the schematic and PCB: View attachment 3441

My version is for both 115VAC and 230VAC by use of a jumper.
It has an optional feedback loop with an optocoupler. You dont have to use this, but its there.
Read this thread (MultiSims messages) for what is necessary for the basic version.

The trafo is a ETD49 with N87 core. I bought them from mouser.com.
Winding info is in the schematic and in this thread. (Again: Scan for MultiSims messages)
All other components are standard and NON SMD.

It is still the first version, a prototype, but if you're interested you can buy one from me.
This will keep costs low and I will make the final version (maybe this one ?) available for purchase too.
I can also supply the trafo. But only in combination with the PCB.

Contact me for shipping costs etc.

Hello. Sory for my English.
How was your start?

hello friends
could some one tell me that half bridge and full bridge smps with one is good to design to get a power of 5kv
thanks

smps problem

Hello friends

I am assembling a half-bridge smps based on SG3525 and IR2110, but when I look at the signal in the primary of the transformer with a minimum useful cycle I get no downtime and have not been able to implement the regulation :ambivalence:. I appreciate any advice I give to solve the problem, in step control pulses turn out well .... I attached a picture to observe what is happening.

for testing I vary the duty cycle manually with a potentiometer.

thank you very much for your help.:UP:

Hi Microsim, im talking about this capacitor, if the value have direct relationship with output power ?? what is the minimum value recommended ??

hi microsim,
i finished detex audio smps 1.2kw with 2 etd49 cores parralleled,
can u tell me what are the equipments need for checking output load,
pls tell me how to ckeck the output for maximum power?

You will need to load the SMPS with dummy load, step by step, and see if it will hold the full load for at least 1 minute.

Equipments needed , beside oscilloscope, digital multimeter

Hope that helps

hi microsim thanks for the reply,
can i load 500w *4 or 1000w *2 halogen lamps for test output?
can u give me ur email, i will send the images to u.

Yes, you can use such load to test the SMPS, if you dont have heater elements, witch is a better option

 

[nazirdigi]

hi microsim, i loaded with halogen lamps and the bulps are very bright and after 1 minute the core copper wire getting very hot, is it ok?

Thats normal, if you use cooper wire

 

[nazirdigi]

can u give me ur email, i can send images of the smps.
what are the other load u mention, iron element ok?

 

[Marshall]

Thank's Mr. MicrosiM.. but i stil heaven't found good quality cores ..after that i'll continue with assembling ..

smps

MicrosiM Hello, I'm trying my resonant SMPS, and I need you to recommend me which values ​​are appropriate for 71kHz, I've noticed that if you use this Hot Trafo resistive load, thanks for your attention.

has anyone tried smps v3.1?is it functional or not?
