I've tried to make it, but every time failed.
I want to see good working IR2153_SMPS. And and want to touch and feel it in my hand.
If some one has it, I'd like buy it. Please contact me.

I'm waiting.
Thank your reply, MicrosiM
Yes, I did. I made 20 more. and I have many dead parts now.
First, MJE13005, 1 TR Flyback. Succeed. But I want half bridge which need no gab. Gab is not easy to me.
Second, IR2153, almost 20 more times, 20 more schema. Recently I recognized I confused the difference of type D and S.
After that IRF840 surived. I used IR2153D, but connected a diode the place between 1 pin and 8 pin. that was the reason to kill the a cup of IGBTs.
And Big CAP killed the IGBT too. Now I use 20 uF 400 volt. Still now I feel horror when I feed electricity initially.
I my smps made very today, failed too. It gave me Only 1 volt DC out. Big toroidal core trafo, pri 24 turn, Sec. 10 turn.
The reason to use troidal core, I wanted to know what turns is better to get high voltages.
I tabbed every turn to be easy to change the turns. Yes, I got it. 6 th turn makes 1.1 volt. 5 th and 7 th 0.7 volt. others are 0.5 volts.
I couldn't believe this. I must wind 2000 turns for 200 volts. This is wrong. But I got such this low voltages sever times. I don't know why.
Ofcouse I winded ei core TDK40 11+11 on pri, 96 turn on sec. I got only 5 volt. I want to send it to someone who could fix it, if there is who.
Ir2153 passions passed 3 years ago in this site.. Nobody makes it todays. And I'm sick of IR2153, My head is headache , but my mind doesn't give up ir2153.
So my head deal with my mind, OK, buy one working IR2153 and make your own one as same as it.
This is the story.
Dear microsiM, do you have one ? Please sell it me. I want to buy that..
Second, IR2153, almost 20 more times, 20 more schema. Recently I recognized I confused the difference of type D and S.
Thanks MicrosiM.
And res_smps, Thanks too.
OK, I'll try on ur recommend.
But, my post which wanting working IR2153_SMPS would be effect until to get anyone's apply, and am waiting.
this is my smps with above schematic
https://www.youtube.com/watch?v=ZmbQ07JOGqs
The store selling relay displayed so many products. Would u please let me know the spec of u used ?
Hi, res_smps. You'v seen my schema. What's wrong with my smps?
Has it trafo problem ?
I have a TDK EI40 core. I posted the core's spec above.
could u design my trafo please? I need two way out, 200 volt DC/0.5A, and 40 volts/ 1 A.
2 x IRF840 are enough. No more IGBTs. Your smps is too big for me.
I offer you.
If you assemble it with following spec, I'll pay 99 us $ including shipping charge.
TDK EI40 core and IR2153D and relay, two IGBTs of IRF840.
No need case and cable. Only assembling parts on the PCB(proto board is OK)
am waiting ur reply.
the circuit also protect circuit breaker in my house from trip when I switch on smps (from inrush current charging primary caps)If u cocern the part, why don't u make that without the relay part. It dosen't matter.
you only need 18 turn not 36OK. I'll remake mine using this result 18 turn.
So, this time I make such like this : pri is 18 + 18 :sec is 10 turns (purpose is to see what voltages come out. Expecting 40 ~60 volts)
Hi, res_smps and all guys.
I got around 80 VDC. from new assembled card this morning 2 o'clock in Tokyo and Seoul time.
But I was not sure exactly what VDC came out, because I turned off soon, seeing the moving hand up to around 80 VDC.
While seeing the meter hand of DC volt, the assembly made smell and smokes. I thought it happened in 5 seconds. I thought the resistor couldn't alive which was protecting in rush current, 100 ohm of 10 W.
I had put that R between NTC and recti diode KBU808.
I bravely(fool) took out the resistor and connected NTC and KBU808. And turned on. And I saw a bright light in the fuse box.
What is the best thing I do?
changing FUSE, IGBTs then what ?
I used 1.5 A fuse. Should I use bigger one, such like as 5A ?
