Abstract Download PDFThis article presents the design of a dynamic wireless power transfer system using a resonant frequency method using multiple power transmitter in parallel with a single inverter circuit for the light duty vehicle to find the efficiency of the dynamic wireless power transfer between the power transmitter and the power receiver. Simulates a dynamic wireless power transfer with four resonant circuit schemes: parallel-parallel, parallel-series, series-parallel and series-series. By adjusting the distance between the circuits of the power transmitter, and the power transmitter and the power receiver at a resonance frequency. From the simulation, the series-series resonance circuit model has the highest power transfer efficiency of 18.56% compared to other with an optimum distance between the power transmitter is 0.04 m and the distance between the power transmitter and the power receiver is 0.15 m.
