Abstract:
This research aims at modifying conventional DC-DC switch mode Single Ended Primary Inductor Converter (SEPIC) with additional snubber circuit across the switching device for various number of inductors so that the converter can operate at acceptable efficiency at different duty cycles. In a practical DC-DC SEPIC circuit, the efficiency is a function of the duty cycle D of the control signal of the static switch of the converter. Since the converter voltage will be stepped up as necessary, the desired higher voltage gain of the SEPIC converter will be attained by using snubber circuit across the switching device.
Description:
First of all, thanks to Almighty Allah for his grace for the successful completion of our thesis.
Secondly, we would like to express our deepest gratitude to our supervisor Major Md Ali Azam Khan, Faculty of Electrical, Electronic and Communication Engineering (EECE), Military Institute of Science and Technology (MIST), for the great mentorship and guidance he has provided us throughout the year. Completing this work would have been impossible if it were not for his constant supervision and support. We are honored to have been under his guidance who has helped us in every aspect a student can be helped.
Additionally, we are grateful to all other Teachers and Staff of the Department of Electrical, Electronic and Communication Engineering (EECE) of Military Institute of Science Technology (MIST) for their co-operation and necessary supports, which were indispensable for our work.
We are also thankful to our families and dear mates for their encouragement and support to achieve our goals.
