2.  What Is MATLAB?
MATLAB® is a high-performance language for technical computing.
It integrates computation, visualization, and programming in an
easy-to-use environment where problems and solutions are
expressed in familiar mathematical notation.
 Typical uses
• Math and
computation
• Algorithm development
• Modeling, simulation, and prototyping
• Data analysis, exploration, and
visualization
• Scientific and engineering graphics
• Application development, including graphical user interface
building

3.  The name MATLAB stands for matrix laboratory
 In industry,MATLAB is the tool of choice for high-productivity research,
development, and analysis.
 MATLAB features a family of application-specific solutions Toolboxes.
 Toolboxes allow you to learn and apply specialized technology.
Toolboxes are comprehensive collections of MATLAB functions (M-files).
 Signal processing,
 Control systems,
 Neural networks,
 Fuzzy logic,
 Wavelets,
 Simulation, and many others.

4. Development Environment.
Set of tools and facilities that help you use MATLAB functions and files.
MATLAB desktop and Command Window, a command history,
Browsers for viewing help, the workspace, files, and the search path.
The MATLAB Mathematical Function Library.
Collection of computational algorithms
Elementary functions Example: sum, sine, cosine,
Complex arithmetic
Sophisticated functions Example:
Matrix inverse,
matrix eigen values,
Bessel functions, and fast Fourier transforms.

5. Sources & Sinks

6. Elements

7. Lines, circuit breakers and transformers

8. Typical Schematic
-Single phase converter

9. Design procedure
step-1
• Type simulink in Mat lab command window
• Simulink browser appears
• Go to file menu
• Click new
• Select model
• Model file open

10. Step-2
• Save the file in the work space with
file.mdl
Step-3
Model file parameters
• Go to simulation
• Select configuration parameters
• Window get open

11. Step-4
Configuration parameters entries

12. Simulation Parameters

13. Step-5
Building a model using libraries
 Select simpower systems toolbox from simulink.

14. Step-6 Finishing the model Step-7 Run The Model

15. Starting Transient Simulation

16. Step-8 verify the result by opening the
scope window

17. View Simulation results

21. Wave
forms

22. • Waveforms
• Output voltage equation
• Ripple factor
• Input Displacement, distortion and power factor
• Firing angle Vs output voltage ..similar graphs

23. Output voltage
• The average output voltage:
The average value of any
periodic waveform v(t) with
period “T” seconds is given by
