Reliable control of high-speed maglev traction motors and power converters is a prerequisite for the stable operation of high-speed maglev trains. Due to the particularity of the high-speed maglev system, a rotor magnetic field directional control strategy with constant excitation and zero direct axis current is usually adopted to achieve independent traction suspension control. Considering the low switching frequency of the traction converter, a three-level topology is adopted. Compared to the two-level, the voltage stress per switch in the three-level topology is only half of the DC bus voltage, and the corresponding DC bus voltage is doubled. With the same switching frequency, the three-level output ripple and harmonics are much smaller. In this paper, traction control simulation models based on two-level and three-level converters are built in MATLAB/Simulink to compare the operation of maglev trains with different inverter topologies and to verify the superiority of the three-level structure.
