Optimal Design of Magnetic Induction Power Taking System for Vehicle Sensors of Maglev Train

Safety, cost and performance requirements formaglev train have driven the development of a wide range of onboard condition monitoring applications, whose bogies are instrumented for real-time measuring of parameters like component acceleration or temperature. Energy harvesting from maglev train has become a viable alternative to primary batteries. In this paper, ANSYS/Maxwell and ANSYS/Simplorer are used to build an energy extraction CT model with a centralized annular iron core and an energy extraction CT model with a distributed coiled iron core applied to the measurement end of the magnetic levitation train sensor to obtain the magnetic field distribution. On this basis, with the goal of increasing the energy extraction power, the parameters are optimized. Finally, the measuring terminal circuit and the overall module of the magnetic levitation train sensor were developed and the system was tested.
