Abstract As a new type of urban rail transit, trams using inductive power transmission technology have got rid of the traditional contact network and use the coupling coil for power transmission. The coupling coil is an important transmission medium, and its configuration and layout should match the target vehicle type while ensuring the transmission performance and stability of the inductive power transmission system. This paper presents a design and configuration method of coupling coil for practical engineering application. From the view of hardware design, considering the output power and efficiency of the system, a coil design scheme for the target vehicle is proposed, which can maintain the output of high efficiency under the proposed control strategy. Based on the actual vehicle parameters and coil configuration parameters, the simulation model is built. The results show that this method can meet the system operation requirements and achieve better power efficiency output. Finally, using the proposed coil design method, a 1.5kW small experimental platform was built to verify the rationality of the design scheme.
