Design a SEPIC Converter

This article tells about what is a sepic converter, how to design it. A SEPIC (single ended primary inductor converter) is a non-isolated DC-DC converter which allows the output voltage to be greater than, less than, or equal to the input voltage,which seems to be similar like buck-Boost converter type, but SEPIC gives positive voltage at the output,whereas a buck boost converter gives negative voltage at the output.In buck-boost configaration output current is continuous, input current is discontinuous, whereas in SEPIC both output and input currents are continuous. Lets find out more in the following links.

World of LaTeX

"LaTeX?? What the heck?" This is what many people say when they hear the word "LaTeX". If you are one among them, then go on and read this post.

Before telling about LaTeX, let me ask you some simple questions.

1. Did you ever use editors like Word, OpenOffice etc for producing your project reports, paper presentations, or journal articles? If so, after typing a few hundred pages, what happened when you inserted an image file in between your paragraphs? My experience in such situations is worst. My friends and I faced this problem when we prepared our undergraduate project reports. All our previous page settings were disturbed when we tried to insert or resize a picture. Once again, we set out to format the entire document.

2. Did you insert some serious Mathematical equations or formulae in your documents? It is a pain in your ass if you do that in normal editors like Word, despite its Equation Editor.

3. How about the quality of your content? I concentrated more on document layout and its appearance. This affected the quality of my content.

One of the solutions to these problems is LaTeX. Simply put, LaTeX is an open source typesetting system. It is especially useful for developing professional and well-structured documents. The main advantage of using LaTeX is that, it allows you to concentrate on your content and forget about the layout; because LaTeX takes care of the actual typesetting (font styles, alignment etc), structuring of your content and page formatting. Though it is a little bit difficult to learn, LaTeX produces high-quality technical and scientific documents easily. Once you learn how to use LaTeX, it makes your life easy.

So much to say about LaTeX. Let us see this in action. Don't expect to learn LaTeX in one day. It needs a lot of patience to master the basics. Go through the links provided at the end of this post to learn more about LaTeX. By the way, don't panic by looking at the code. It is provided to show how easy it is to produce quality reports.

Installation: To install LaTeX under Windows, follow this procedure -- Download and install basic MikTeX. Install a LaTeX editor like TeXnicCenter. Copy and paste the code given below in an empty document inside TeXnicCenter. Save the file as "demo.tex", without quotes.

\documentclass[11pt]{article}
\usepackage{palatino,url}
\usepackage{amsmath}

\begin{document}

\author{Trisul Kanipakam}
\title{\LaTeX\ example}
\date{\today}
\maketitle

\section*{Hello World!}
This is a sample \LaTeX\ document. We can generate an article like this with a default font size of 11pt, using \textit{Palatino} font. Note that, i don't have to format section headings, justification, numbering of sections and pages etc. We can easily generate tables and center them,\\

\begin{center}
\begin{tabular}{cc}
\hline
Sno & Data \\
\hline
1 & 1000 \\
2 & 2000 \\
\hline
\end{tabular}
\end{center}

Listings can be generated as shown below:
\begin{itemize}
\item \emph{$e=m*c^2$},\quad $\sqrt{4}=2$, \quad $\int_0^2 \zeta^{2}(x) \, dx$, \quad $\frac{dy}{dx} \rightarrow 0$, \quad $\alpha \neq 0$, \quad $F(x_{1}, x_{2}, \ldots , x_{n}),$ \quad $(u, \infty)$, \quad $\lim_{x \to \infty} f(x)$.
\item Matrices and Limits
\[
\lim_{x \to a} \frac{f(x) - f(a)}{x - a}, \quad
\begin{pmatrix}
a & b & c & d\\
x & y & z & w
\end{pmatrix}
\]
\end{itemize}

\begin{center}
\textit{Have a nice time learning \LaTeX\ !}
\end{center}

\end{document}

% End of document.

If everything goes well, you should see something like this.

Now Build the current file in TeXnicCenter to produce a nice looking pdf file as shown below.

Thats it. Forget the WYSIWYG editors and enter the world of LaTeX.

Buck-Converter Design Demystified

Hi,

This is one of the most simplest and useful articles, the author explains the buck converter
design in a simple way. After reading this article you will understand the buck converter design
and able to design the buck converter. He explains about the selection of the, inductor,mosfet,input and output capacitors,diode, with relevant equations.

Personally i feel that it is very useful for basic learners in the design field.
