Third year project proposal submitted in partial fulfillment of the requirements of the degree of Bachelor of Engineering Dedication
For my family and my girlfriend who offered me unconditional love and support throughout the course of this thesis. I would also like to thank my supervisor without your time and advices, this project would not have been possible.
The objective of this project is to produce a supercapacitor hybrid system for DC motor control pulsed power circuits with demonstration of elapsed time using airborne remote controlled helicopter. The expected results for this experiment is for the battery to have a longer run-time with the used of supercapacitor. The thesis first explained the definition of supercapacitor and the construction of the supercapacitor. Next the thesis discuss on the needs of supercapacitor with higher capacitance. The thesis then shows the difference between batteries and supercapacitors followed by the different amount of supercapacitors which provides higher capacitance. Next, the software simulations are done with 3.1 Cadence_SPB_16.3 and results are shown. Hardware is designed and soldered onto the circuit board. Lastly, the field testing for the remote controlled helicopter is done.
First and foremost, I would like to express my sincere gratitude to my supervisor Prof. SRS PRABAHARAN for the continuous support of my final year project, for his patience, motivation, enthusiasm, and immense knowledge. His guidance helped me in all the time of research and writing of this thesis. I could not have imagined having a better advisor and mentor for my final year project.
Besides my supervisor, I would like to thank my final year project moderator Dr. KENNETH ANG for his encouragement, insightful comments, and hard questions.
My sincere thanks also goes to the university project laboratory Mr. Hashimi, for offering me help in some design work and component supply.
Last but not the least, I would like to thank my family: my parents ChuanJoo Lee and SheueChing Tan, for giving birth to me at the first place and supporting me spiritually throughout my life.
