CONVERTER FOR WIRELESS POWER TRANSFER IN ELECTRIC VEHICLE BATTERY CHARGING SYSTEM

Electric vehicle does not require oil consumption and it does not emit gas pollutants as it uses electrical engine to run its system. Electric vehicle provides the solution for the awareness of the limited fossil fuels and environmental issues such as green house gas emission. The technical solution of the electric vehicle charging system is one of the challenges because it does not have standard solutions. In the future, wireless charging system is the best method of electric vehicle charging system compared to the conventional plug-in or conductive charging as it offers more convinient, faster and user friendly of charging system. This paper addresses the design of the converter for wireless power transfer in electric vehicle battery charging system. A research studies about electric vehicle charging system was made and all related theories and information are gathered in a literature review. With the pre-planned methodology that was made to guide the project flow, a converter design is develop from a resonant converter basic design approach using PSPICE simulation by determining the current and voltages, in several points of the circuit. The project has proved that by using this method, a variable DC output voltage of the converter can be obtained by controlling the value of the switching frequency. With this characteristic, the objective of the project has been achieved. However, a further research on rectifier for very high frequency should be made to improve the power transfer efficiency which is very significant in the circuit design.
