1kW smps project (based on MicrosiM design)
- Thread starter ludo3232
- Start date
its was pull out from tetra pack power supply with high rated IGBT
Hi Microsim and Ludo, Great design . I want to make one but i want at most 300 W at 12 V as bench supply for my robotics.. I have never made an SMPS before so can I use this design to get a 300 W smps or this design will be an over kill for my needs ?.
And as I don't need more power how can I make this Design more cost effective say by using smaller core than ETD49 etc ... or is there any other DIY project for less than 400w SMPS.
As for experience in Electronics. I know about Digital electronics never went to power side so I am fairly new to this thing..

I am not sure if PC power supply will work for your application? or you need variable Voltage / Current?
Hi Microsim,
I have decided to work on this one... Although there are many DIY related to modifying PC PSU to get such supplies those will always remain a mystery if they break down as to why did they broke down.. This project is crystal clear we have AC to DC conversion then a high frequency PWM generator connected to Mosfet driver to Mosfets which currently are switched at 50% pwm going to tansformer which gives us isolation from mains to again ultra-fast rectifier to filters and we are done also there is Short circuit protection too which i have to see how it is working .... what I will do is take output to 15 V from SMPS and add voltage regulator to get 12 V ....

Hi I am going to use the version 3.11 PCB layout by ludo directly. I am not going to modify anything... and here is what I Intend, the circuit I am showing in attachment I got info about it from http://hmin.tripod.com/als/fsmyth/pages/analogs6.html#APS627 : will help me even get a variable regulated output at high currents ... so I need to make a smps which gives 36 V output at 300 - 360 W and then i will add this circuit to out put of SMPS to gain a variable power supply. I haven't fine tuned this circuit so there will be few errors. So my question is can I attach this circuit to output of Ludo's SMPS ?

I have to take a look at the schematic if you have it or the amplifier first.
HI MicroSim what about this core page #579
Very nice core indeed, why dont you give it a try?
i expect 1.5 ~ 2Kw from that nice core !!
