摘要
Transmitter coil is one of the most critical part in an inductive power transfer (IPT) system for electric vehicles (EVs) application. For the traditional transmitter coils, due to the switch process between the adjacent coils, two serious problems of pick up voltage fluctuation and high power loss on the windings affect the stability and efficiency of the wireless EV charging. In order to solve these problems, this paper proposes a novel segmented transmitter coil for wireless power transfer on EV. A mutual inductance model is established based on the Neumann's Formula, moreover, a key parameters selection method and turns ratio optimization method of the proposed segmented transmitter coils are also presented to keep the mutual inductance in a constant level while the transmitter coils switching one by one. Both of the simulations and experimental results verify the validity and effectiveness of the proposed transmitter coils and its key parameters selection method.
