Here I've attached an Excel sheet to do the calculation for "Flyback smps". I don't have experiance of designing a flyback smps. Please give me your feedbacks and suggestions for any corrections. Udhay
Hi, I learning smps design with help of tutorials. I found this book "Power Supplu Cookbook By Marty Brown". There is one example calculation for 65W smps construction. I try to understand the design & calculation, but now I need some help to understand this. The Example file & datasheet of the (...)
Hello, The attached (LTspice sim and pdf schematic and excel design doc) show a DCM Full Bridge smps with Vin=390vdc Vout = 400vdc Pout = 100w Fsw = 100khz DCM The actual exact leakage inductance value in the transformer plays a big part in the design calculation. This is because the secondary side transformer (...)
Hi guys first i want to tell that my english is not good because i'm from itay :) my problem is calculating transformer details (primary and secondry turns) i'm using this circuit: 107864 HERE ARE THE PICTURES OF WAVEFORMS: ON GATE DRIVER MOSFET: 107866107867 O
Friends i need the details for Ferrite transformer winding. I am working in the smps design, i need a help for ferrite transformer calculation. Please help me. smps input: 230Vac output: 12Vdc / 1Amps Please help me for, what are the spec i need? How to calculate primary & secondary winding (...)
Dear Kashif Hi Is it important to use iron core ? why not an smps ? you need just 110 volts 50A ? right ? 5.5kW ? if yes , you can use a simple H bridge . best Wishes Goldsmith
Hello i want to winding my smps transformer.i have three kind of wire (.20 , .15 , .10) and EI25/19 core.and i going to make forward transformer with Pout=60(15 volt,4Amper) and my frequency is 50Khz.could you tell me the calculation and how i can do it? Thanks
Dear meysaminter Hi it is pretty simple . what are the specifications of your smps ? out put voltage and current and frequency of operation . Thus i can help you as well . Best Wishes Goldsmith
I designed some smps transformer based on practical method. But the problem is if I change one turn +/- total performance changes a lot. I need the calculation method. Can anyone help me in this case please?
hey guys... I want tutorial for designing of smps transformer... if any one has tutorial regarding my this post then please post here.... ---------- Post added at 19:02 ---------- Previous post was at 19:01 ---------- please give me help....
I need smps output transformer design calculation. Where should i refer? Please guide me some link or direction.
hi guys, i want to make a toroidal iron core transformer.i have searched the net but found nothing .calculations are available only for smps toroids i have made transformer with ei cores.with the help of this eq n(pri)=ex10^8/4.44nfab i want to make 600va 50-0-50 in toroidal iron core with what are the (...)
Hi For designing power transformers using CRGO and low cost core, normally we use some simple formula which relates transformer cross sectional area, core permeability and some turns/volt etc. Such simple calculations are practically sufficient for our purpose. Just like that is there any easy method for claculating (...)
