Description
Summary:This paper investigates the optimal distance between the transmitter (TX) to transmitter (TX) and Transmitter (TX) to Receiver (RX) of various shapes of coils. The study examined the complexities of WPT-DCS implementation, focusing on magnetic flux distribution, coupling factor, RX efficiency, RX power, mutual inductance, and the impact of spiral geometry's thickness. The findings emphasize the importance of considering factors like frequency, distance, and coil thickness in designing and implementing wireless charging systems for EVs. It was found that a square spiral coil achieved the highest efficiency (87%) and the efficiency of a circular spiral coil was minimal (44.8%). The study aims to conduct a literature review on coil design and shape in WPT systems, analyze magnetic flux distribution, study distance between multiple transmission coils and transmitter-to-receiver coils, and optimize distance using coupling factor and efficiency parameters.
