Description
Summary:Inductive power transfer (IPT) system for medium-low speed maglev train can effectively overcome the drawbacks of traditional contact power supply system. However, in the existing IPT system, the primary track is excited by single inverter. When the inverter fails, the IPT system can not supply power anymore which will lead to shutdown of the maglev train. In order to improve the reliability of power supply system, three novel IPT system topologies based on double-ended inverter is proposed in this paper. The primary track can be excited by both double-ended inverters simultaneously or either of them independently. The output voltage and current characteristic of the asymmetric LCC-S topology is analyzed in detail. Finally, the effectiveness of the system is simulated for a power level of 30kW. The results verified the performance of the proposed IPT system.
