In this paper, a 3D multi‐source GBSM model is proposed for the vacuum tube scenario using LCX. By equating the periodic slots to multiple magnetic dipole antennas, the electric field distribution of LCX is deduced, and the CIR expression is derived. Based on this, the multi‐link spatial‐temporal correlations, including the spatial CCF and temporal ACF,

Numerical Analysis of the Rotational Magnetic Springs for EDS Maglev Train
Different from the traditional railway trains, the combined levitation and guidance EDS maglev train is more likely to rotate after being disturbed. Therefore, the rotational electromagnetic stiffnesses are significant operating parameters for the train.

Inching control of Superconducting Maglev Train
In the Yamanashi Maglev (magnetic levitation) Test Line, running tests commenced on 3 April 1997, and have progressed well. The world record 552km/h run of manned 5-car unit was attained on 14 April 1999. “Reliability verification tests” are being planned for fiscal 2000.

This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have

Research on Lightning Coupling Rule of the Equipment Port of Maglev Train
Compared with the traditional wheel-rail train, the maglev train is more vulnerable to lightning strikes due to the lack of contact net protection. In severe cases, it will cause damage to the vehicle-mounted equipment and affect the safety of the train.

ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...

Modelling magnetic levitation (maglev) train [PDF]
"Maglev‟ represents magnetic levitation. The magnetically levitated train has no wheels, but floats on an electromagnetic wave. Maglev is trains that run on magnets in a certain way so that they are equally levitated.
