title = "Multi-Objective Optimization of Single-Transmitter Coupled Multi-Receiver IPT System for Maglev Trains",
abstract = "Inductive power transfer (IPT) is an effective energy supply option for maglev trains that currently depend on pantographs to obtain enough electricity. This paper demonstrates a multi-objective optimizing method of a single-transmitter coupled multi-receiver contactless charger for maglev trains. The 3D FE model is built to obtain parameters of the magnetic coupler, and the power loss model is given to calculate the loss and efficiency. Under the given restrictions and boundaries, a multi-objective optimization process of IPT coils for maglev trains is proposed based on Pareto optimal theory. High efficiency, high power density, and low cost are selected to be the design objectives. The arrangement of ferrite is included in the process to optimize coil design in an all-sided way. A reasonable optimal solution is selected from the Pareto fronts and its detailed information is given. A scale down single-transmitter coupled dual-receiver IPT system was constructed to verify the design considerations. The efficiency of the prototype reached 80% at the condition of 1kW output power with around 100V input voltage and 50V output voltage at the switching frequency of 85kHz.",
