Minimizing Leakage Magnetic Field of Wireless Power Transfer Systems Using Phase Difference Control

Energies, 2022
In this paper, we propose a method to reduce the leakage magnetic field from wireless power transfer (WPT) systems with series–series compensation topology by adjusting the phase difference between the transmitter (TX) coil current and the receiver (RX ...

A Magnetic Field Concentration Method for Magnetic Flux Leakage Detection of Rail-Top Surface Cracks

IEEE Access
Magnetic Field Leakage (MFL) is one of the prominent methods used to detect rail top surface cracks. However, it has been shown that detecting narrow rail top cracks is a major challenge because of their weak magnetic leakage fields.

Magnetic Field Leakage of HTS Medical Accelerators [PDF]

Journal of Physics: Conference Series, 2020
Abstract A high temperature superconducting (HTS) magnet used in medical accelerators was designed with combined function for bending and focusing/defocusing, through a layer-by-layer design process. The six-layer combined function magnet produced by the layer-by-layer design process reduces the total volume of HTS material required ...

Study of leakage currents in PC CVD diamonds as function of the magnetic field [PDF]

physica status solidi (a), 2009
AbstractPolycrystalline diamonds produced with the chemical vapor deposition technique (PC CVD diamonds) are regularly used as beam loss monitors in accelerators by measuring the ionization of the lost particles. In the past, these beam loss monitors showed sudden increase in the dark leakage current without beam loss and these erratic leakage currents
