My new 1.5kW SMPS Some reviews

[phoenix87]

Hi
I have developed a 1.5KW smps for class AB amps . It is still under testing will publish results .
Topology used :- Full bridge .
Output :- +-95V @ 15A
Input Voltage :- 230VAC @ 50Hz
Features :-
1. Input Over Voltage Protection
2. Short Circuit Protection
3. Over Temperature Protection
Some Pics Attached :-

Regards
Phoenix 87

Can u post a schematic?

 

[qusp]

was the SMPS moving?

as mentioned above, without a schematic and with every single photo being blurry, its almost impossible to make any comment, even though the idea of a 1.5kW supply for class AB is interesting

 

[Boscoe]

95+95*15= 2890KW?

I like you have specced it for single rail operation at one time which is in reality how it will be used.

 

[marce]

Creepage and clearance?

 

[clocktower]

+-95VD @ 15A ?

That sounds good, but for how many minutes?

regards

Hello,

would it be possible that you provide the schematics? i'd need to built an smps like that too.

greets from vienna

Hi phoenix
greetings can i use ETD59 instead of EE 55 core

nice work

smps power supply with pcb lay out

Can we get PCB and schematic?

 

[basreflex]

there is an error on the schematic. one of the negative rectifiers in the output is connected reversed.
you need to add PFC to make this work properly. a resonant design has less stress on the igbt's as the leakage inductance of this design will give you quite some ringing.

Hi Basreflex
greetings can you share any good high power smps schematic to diy
simple one
warm regards

[basreflex]

sorry , I don´t have one.
a good starting point is the nxp resonant controller/pfc combo IC.
the nxp design tool is very instructive and gives transformer design details.
it iss limited to approx 350W, intended fro tv sets etc.

from there you can redesign the stages to accomodate the higher power.
even if you have a schematic, good physical design/layout is key.
good luck.

sir andrewlebon what type of ei core the you are using there is a gap or not?

Hi, do you have a schematic to us? thanks.

 

[Adnancoskun]

Ofcourse, i wanna share it at here. I have got PCB too, but ı don't know, how i can share PCB with proteus..
