Design and analysis of dynamic wireless power transfer for electric vehicle charging application

The depletion of oil and the emission of greenhouse gases are getting attention worldwide. The transport sector is one of the major causes in producing greenhouse gases next to the industry sector. Electric Vehicles are a promising solution to minimize the negative impacts caused by conventional vehicles on the environment. However, problems associated with introducing EVs arise, such as inadequate charging facilities. The wireless charging system can make EVs more accessible. This mode of charging allows the battery to get charged from the power source without the electric cables and wires. This paper proposes the design and simulation of parallel-parallel configuration for the dynamic charging. ANSYS Maxwell software is used for design and simulation of the coil. The power transfer between the transmitter coils and receiver coil is tested by taking the parallel compensation. The system is simulated and demonstrated for 5cm air gap between the coils. The output waveforms has 18.9 kHz frequency. A DSO is used instead of multimeter as the work deals with high frequency. The DSO is used to measure output voltage across load and thus power transmitted was calculated. In this work, the misalignment between transmitter and receiver coils also improved.
