## Can you explain this SMPS example calaulation

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 transformer core also attached here. From that

## hi genius.. Need some help in power supply design?

There are lot of material available over internet on this topic. I am suggesting you the books which I found useful (1 to 3 below). Also there are lot of application notes - 4 to 6 are something which are very basic. Hopefully they will be helpful to you. 1. Power supply cookbook ,2nd edn, marty brown, EDN Series 2.

## flyback transformer design problem

hello im trying to design flyback transformer with marty brown book formulas . it has two formulas in CGS and MKS system as it says . ive just put same values in these two and getting different results . what im doing wrong? 107162

## What is a pole in an error amplifier of an smps?

Hello, Is it a specific frequency, or is it a trace on a bode plot? In marty brown book he shows an RC circuit and shows bode plots for it and says it is a "pole"..........but what is a pole? Is the pole the frequency at which the voltage transfer function through the RC circuit goes down by 6dB?....or is the RC circuit itself a pole?.....or

## swich mode power supplay

Hi darkbloodshed, I'd suggest you to search in Internet for the book Power Supply Cookbook, from marty brown, it is an excellent book, here is explained all you need to know from a very basic perspective, with design examples included. Let me ask you, are you planning a variable power supply?

## how to increase efficiency of battery charger

For high efficiency of the charger itself, use a switching power supply. For high efficiency charging, use 4-step (or 3-step) charging. A good start to switching power supplies would be to read marty brown's book "Power Supply Cookbook". For battery charging techniques/algorithms, check this out:

## How to build own transformer?

Hi, These are taken from marty brown's "Power Supply Cookbook": Npri = (Vinnom * 10^8) / (4 *f * Bmax * Ac) Nsec = / (Vinmin * DCmax) f - frequency in Hz Bmax - flux density in gauss (webers/cm^2) Ac - effective core cross sectional area (cm^2) Vfwd - diode forward voltage in V Npri - primary no. of turns Nsec - secondary n

## Power Electronics Course Design Question..??

Such courses will not enable you to design a switching power supply professionally ( it will give you a solid knowledge about it); but the following 2 books will: Practical Switching Power Supply Design by marty brown Switchmode Power Supply Handbook by Keith Billings
