摘要：	Due to the recent development of technology in power electronics and smartappliances wireless power transfer developed significantly.The further development inthe field of wireless power transfer a new trend was introduced to charge an ElectricVehicle with wireless power transfer while in motion.Electric vehicle dynamic wirelesscharging system is the improved version of stationary charging of Electric vehiclethrough wireless power transfer.Wireless Power Transfer is a technology whichtransfer efficient electrical power without using wires over large air gaps.Due to thisreliable technology combustion Vehicle is diverting to Electric Vehicle to reducepollution and get clean environment. 　　This thesis is the research work on Electric Vehicle Dynamic Wireless ChargingSystem which is based on wireless power transfer magnetic resonant coupling.Thisthesis present electric vehicle charging while on move.The topology used for electricvehicle dynamic wireless charging system is to get power from primary coil with airgap and charge the battery of vehicle while it is moving.For this purpose two coils arenecessary one is primary and the other is secondary coil.Primary coil is buried underthe road and connect with power supply back from grid and secondary coil is connectedunderbody of electric vehicle.High frequency is used for getting high transferefficiency.Designing of coil and its analysis is performed in this thesis.Short segmentrail structure is design for Electric vehicle dynamic wireless charging system.The coilfor wireless power transfer which in this thesis designed in software and gets its result. 　　The result for coil design was based on parameters and then checked the result ofmagnetic flux and vector direction from coil designing simulation.Furthermore in thisthesis another software for comparing the results with different parameters was used. 　　From the simulation in this thesis the result for Power vs Frequency is obtained,Transfer distance and Load resistance and Efficiency vs Frequency, Transfer distanceand Load Resistance.Next worked on Power stability control strategy which in thisthesis used to stable the power while the vehicle is moving.Three Power controlstrategy is used for stable power.This strategy is the ability of the system to maintainsteady state voltages at all the system when disturbance occur.(1) Self-adaptive sourcevoltage control strategy is used when an EV in need of charge enter the power track oran EV leaves the track then the amount charging Electric Vehicles will change.(2)Constant source voltage control strategy is used when there is congested traffic andsufficient power cannot be provided when there are too many charging Electric Vehicles.(3) Particular Power Demand Control Strategy is used for urgent charging request for aparticular Electric Vehicle whose battery charging capacity is very low.
