Buck converter Basics Notes for Designing and Implementation - PART 1 Gathering Info & Calculating Parameters

I am planning to simulate and implement a buck converter in an bread board.So I was searching all over the web for good material to understand and design it.I could find that none of the texts followed at universities is not good enough for implementation of the circuit physically(I really dont understand the reason the universities provide us with such texts to follow and judge every one based on the marks they get by following such texts --- Ever have you wondered why the students with low marks who tries perform so badly... Just think of this context.) Anyway I was able to find many such papers from internet explaining the basics of it and I found this particular one very easy to understand and follow.I must really thank Bob Dildine who is its author to prove its not rocket science but its all about the concept and less about the equations thats proves it. Notes I made while designing the buck converter using the above mentioned(Link to download the Buck Converter basics Notes ...

Buck converter Basics Notes for Designing and Implementation - PART 2 Simulation

Image
Tried simulating with Qucs The simulation didn't come of well as I hoped.The Output is showing some kind of  waveform I have no idea of looking at how it became so. Simulated Circuit using IRF Z44 Mosfet (Now Vishay MOSFET Z44 )     Simulated Circuit using IRF Z44 MOSFET (Vishay) Waveform I got for Buck Converter Circuit     Now After trying the same in TINA spice simulator from Texas instruments I couldn't successfully produce an output.As I remember from the "Buck converter demystified" reference the ripple current will be maximum at the 0.5 duty ratio.So I have decided to redesign the parameter values for a different duty ratio of 0.25.   New parameters are;     Duty Ratio : 0.25   Period of Switching cycle (SW1) : 20us   Time for which SW1 is ON :0.25*20us = 5us   Ripple Current : 0.33*0.6 = 0.198A   Inductor : 454.54uH   Capacitor  at output (@ 100mv overshoot ...

Integrating by parts(To find integral of product of two functions)

Image
Integrating a product: integration by parts. Suppose we want to integrate Xsin(X). We can integrate each of these functions separately, but how do we integrate the product of them? The answer is we use a technique called "integration by parts". First I'll tell you the formula, then show you how it works with that particular example, and then explain where on earth the formula came from! Here's the method. We have a product of two functions and we want to integrate this product. The first step is, we have to choose one of them to be integrated and one to be differentiated. (The result will be that the whole product gets integrated, but to get there we actually have to differentiate one of them. It seems strange but you'll see why later.) So we choose one to integrate and the other to differentiate. To remind us which one we're going to integrate we'll write it as the derivative of something, let's call it dv/dX, so when we integrate i...
