Rectifiers

RECTIFIERS 

Introduction

All electronic circuits need dc power supply from battery or power pack units.It may be economical anc convenient to depend upon battery power supply.hence, many electronic equipment contain circuits which convert ac supply into dc voltage at the required level.The unit containing these circuits is called Linear Mode Power Supply(LMPS).In certain applications, dc to dc conversion is required. Such a power supply unit that converts dc to ac or to dc is called Switch Mode Power Supply.

Rectifier

It is defined as an electronic device used for converting ac voltage into pulse rating dc voltage.It consist of PN junction diode which is polarity sensitive.when the diode is in forward bias, the diode 'D' conducts and allows the current to flow through it. It without any resistance i.e diode is on state.
When the diode is in reverse bias it doesn't conducts then no current flows through it, i.e diode is in 'off' state providing a blocking function.thus the ideal diode acts as a switch, either open or close depending upon the polarities(bias) of the voltage across it. An ideal diode has zero resistance under forward bias and under reverse bias having infinite resistance.
Rectifiers are classified into different types:

Full Wave Bridge Rectifier With Capacitor Filter

 Full Wave Bridge Rectifier With Capacitor Filter The voltage obtained across the load resistor of the full-wave bridge rectifier described above has a large amount of ripple. A capacitor filter may be added to smooth-en the ripple in the output, as shown below. Figure 21: Full wave Bridge rectifier with capacitor filter The rectifier circuits discussed above can be used to charge batteries and to convert AC voltages into constant DC voltages. Full-wave and bridge rectifier are more commonly used than half-wave rectifier.

MATLAB

Introduction to MATLAB Goal The goal of this tutorial is to give a brief introduction to the mathematical software MATLAB. After completing the worksheet you should know how to start MATLAB, how to use the elementary functions in MATLAB and how to use MATLAB to plot functions. What is MATLAB? MATLAB is widely used in all areas of applied mathematics, in education and research at universities, and in the industry. MATLAB stands for MATrix LABoratory and the software is built up around vectors and matrices. This makes the software particularly useful for linear algebra but MATLAB is also a great tool for solving algebraic and differential equations and for numerical integration. MATLAB has powerful graphic tools and can produce nice pictures in both 2D and 3D. It is also a programming language, and is one of the easiest programming languages for writing mathematical programs. MATLAB also has some tool boxes useful for signal processing, image processing, optimization, etc. How ...
