Abstract: The development of electric transport and its charging infrastructure is cutting-edge, including for industrial applications. Underground suspended monorail is a mining transport that is also trending to implement battery-powered locomotives. The promising way for their charging is using a dynamic wireless charging system built with a long line on the transmitting side. For such systems, the influence of compensation topology on the operation quality is poorly studied. The article investigates four two-element topologies. As the performance indicators, the following are chosen: the efficiency of wireless power transfer and the transmission ratio, which shows the ratio of the resonant circuit output voltage, indicating the load voltage, to the resonant circuit input voltage. For each topology, the mathematical model is compiled and the parametric equations describing the performance indicators are obtained. An analysis of the performance indicators of the dynamic wireless charging system with different compensation topologies was made, taking into account the features of the underground suspended monorail. Based on the obtained results using the analytic hierarchy process, the best topology for the conditions under consideration was selected.
