Research on Power supply Feasibility of Super Capacitor Tram based on Wireless power Transmission

: The traditional super capacitor trolley car usually uses the contact rail or the third rail to power the power supply. In this method there are some problems such as brush wear arc produced by the broken rail and large friction heat. Therefore, a prototype design of wireless energy transfer device for super capacitor trams is studied in this paper. Firstly, the system structure and circuit topology of the device are studied; secondly, according to the function of super capacitor trolley car and the requirement of output input characteristic, the system transmission efficiency and space magnetic field vector of the device are obtained by simulation analysis; finally, the system efficiency and transmission distance of the device are verified by setting test. The simulation and experimental results show that: the system efficiency of the wireless power transmission device proposed in this paper is about 80%, which can meet the power supply demand of the super capacitor tram. It is feasible to replace the contact rail with wireless energy transmission technology.
