| 520 | |a As the population growth, people will consume more of natural resources. The depletion in energy sources especially oil is among the crucial issues nowadays in Malaysia. Since the quantity of vehicles in Malaysia are increasing, the oil sources are not enough to accommodate all. It is precited that on 2051, Malaysia will probably run out of oil. Wireless charging of EV has been developed but it gives limited performance due to issue like misalignment, air gap and power loss. Therefore, this project has proposed three coil pair design (P-S1, P-S2, P-S3) of circular pad coupler for wireless charging of electric vehicle (EV). These three pairs were tested for air gap and misalignment cases using simulation and experimental work to find the best coil pair which gives the highest efficiency of power transfer. To design the circular pad, three elements are required in this project. The elements are circuit parameters, geometric properties and experimental work. At first, the circuit parameters are calculated using a specific equation. This is important to obtain the inductance value for primary (Lp) and secondary coil (Ls) at resonant frequency which is needed for the fabrication of coil process. The simulation for ideal case were done using NI Multisim software to prove the calculated corcuit parameters. Next, the overall system circuit was simulated that gives the average efficiency of 96.1 %. Then, the geometric properties were calculated and designed in JMAG Designer software. Before designing the circular coil, several geometric parameters like inner diameter (Din), outer diameter (Dout) and number of turns (N) were set up and calculated. Here, the magnetic flux density and power transfer were observed and measured for each coil pair design. From the simulation in JMAG Designer, it shows that P-S2 pair gives the highest efficiency of 96.6 % for power transfer. Lastly, an experimental work is setup and performed in Electronic and Instrumentation Laboratory, IIUM. Three coil pairs were fabricate manually using AWG 18 copper wire. The current and voltage at primary and secondary side were measured in order to calculate the efficiency of power transfer. The results portrayed that P-S2 coil pair has the highest power transfer efficiency of 90.4 % than P-S1 and P-S3 pair at different misalignment condition. From the results taken for each air gap and misalignment cases, P-S2 coil pair gives the highest efficiency of 95.48 % at air gap 6 cm and misalignment 0 cm. These experimental results are tally with the power transfer in the simulation Therefore, the design of coil pair that gives high power transfer efficiency is the coil that have the same outer diameter for both primary and secondary side whilst the inner diameter of secondary coil is bigger than primary coil. The limitation for this study is that the high cost of copper wire and limited equipment in the laboratory. | ||
