WEEK 10
OBJECTIVE: To attend and present the Project Proposal.
PROCEDURE:
The Final Year Presentation I (FYP I) took place in the Dewan Gemilang, Unikl British Malaysian Institute (BMI) on 22nd of November 2013. The presentation started at 2:00 in the evening. I was assigned to two assessors from the FYP committee whom are lecturers from the electronics and Communication Section. My assessors are Sir Muhyi Yaakop and Miss Nurul Husna.

The first
assessor is Sir Muhyi. I am the first one presented my project proposal in my group which consist of 6 candidates. The presentation went well and smooth. I managed to answer all the question asked by Sir Muhyi, but the mark is all on Sir Muhyi as how he evaluate my presention.
The second
presentation with Miss Nurul also went well. Again, I successfully
answered her question during the Q&A session except for the last question about my real output design. She does suggested
to do discussion with my supervisor, Madam Zaridah about that matter.
CONCLUSION:
i successfully managed to attend and present my project proposal. This is a good thing for my project as the presentation went well. The mark from the presentation will be add to the total mark of FYP 1.
Friday

Wednesday
WEEK 8
OBJECTIVE: Further research on the resonance inductive coupling theory.
PROCEDURE :
The dateline of project proposal presentation just around the corner. Well preparation should be done early especially on the basic system of wireless power transfer.
1. Induction coupling method:
Inductive coupling method is the work of power transfer from transmitter coil to the secondary coil. it can be understand with animation video below.
The video shows how the wireless power works using two coils. However, the effect of transferred power will be less efficiency due to the power is transmit in varying direction. Some modification need to be done to ensure high efficiency of wireless power transfer. One of the modification that can help increasing the efficiency is the electrical resonance.
2. Resonance help increase wireless power transfer efficiency.
Resonance occur when an object vibrate at certain frequency which is the natural frequency of second object resulting the second object receive the vibrating energy from the first object.
In electrical resonance, capacitor is use to help tuning specific frequency in a circuit. For wireless power transfer, the capacitor is put at both transmitter and receiver circuit. So that, both circuit will works in matching frequency. The transmit power loss will be reduce as the receiver will get most of the power transfer before the power loss in the induction system through many cycle.
3. Works of resonance frequency.
The resonance frequency will work only on the equal value of capacitive and inductive reactant
in a circuit.
CONCLUSION:
The good explanation and firm basic of wireless power transfer can be helpful in the project proposal presentation.

WEEK 7
OBJECTIVES: Identify the important elements in designing project, expected output and theoretical calculation.
PROCEDURE:
This project is expected to give smooth output of power transfer wirelessly. I had met my supervisor to discuss about the output of this project. From research and discussion with supervisor, i came out with the theoretical calculation as followed:
1. The most important element to be design is the transmitter and receiver coil. It is include the design of diameter and the displacement between coil. It is as below:
Transmitter design : 30cm of transmitter coil radius.
Receiver design : 10cm of receiver coil radius.
Displacement between coil : 20cm
The quality factor, Q for both coil theoretically set as 100.
2. The design of transmitter coil must be accurate to get the value of 20mH for transmitter coil and 6.7 mH for receiver coil.
3. The coupling coefficient for both coil is calculated using below formula:
k =
= 0.46.
where, rT = transmitter coil radius, rR = receiver coil radius, a = orientation between coil (set as 0 degree to get maximum effeciency), and x = displacement between coil.
4. The theoretical expected about can be calculate using the system efficiency as below formula:
Input power = 4W
System efficiency =
= 95%
so, the expected output will be 3.83W.
CONCLUSION:
The theoretical calculation shows high efficiency (greater than 80% efficiency) for the system. As the expected output will be achieved in the next practical design of project.
