IEEE Transactions on Electromagnetic Compatibility, 2020
A novel design of active coil shielding is proposed to reduce the magnetic field generated by the currents flowing into the coils of a wireless power transfer (WPT) system for charging the batteries of an electric vehicle (EV). The main idea is to divide the traditional active loop used to shield a source in two separate shielding coils so as not to ...

Low Noise Active Shield for SQUID-Based Magnetocardiography Systems
IEEE Transactions on Applied Superconductivity, 2018A light weight and low-cost active magnetic shield system is proposed for a single channel SQUID-based magnetocardiography system equipped for operating at liquid nitrogen temperature without passive magnetic shield. The developed active shield, using coils around the sensors, is a two-stage magnetic shielding system, each stage of which has been ...

Active Shielding Design of Patrol Robot Wireless Charging System
2019 IEEE 3rd International Electrical and Energy Conference (CIEEC), 2019The wireless charging technology (WPT) is a hot research topic at present. Because of its plug-in-free feature, it is very suitable for patrol robots. In order to reduce the influence of wireless charging coupling mechanism on electromagnetic environment in non-working area, a shielding device was designed and its finite element model (FEM) was ...

An actively compensated 8 nT-level magnetic shielding system for 10-m atom interferometer
Review of Scientific Instruments, 2021We design and develop a high-performance magnetic shielding system for a long baseline fountain-type atom interferometer. The shielding system is achieved by a combination of passive shielding using permalloy and active compensation with coils. An 11.4 m-long three-layer cylindrical shield is completed by the process of welding, local annealing, and ...

IEEE EUROCON 2021 - 19th International Conference on Smart Technologies, 2021
The problem of reducing the magnetic field generated by a group of overhead power lines by means of active shielding is considered. First, a metamodel of the magnetic field generated by a group of overhead power lines was synthesized. The task of synthesizing the metamodel of the magnetic field is reduced to a zero-sum antagonistic game. The components

An actively shielded gradient coil design for use in planar MRI systems with limited space
Review of Scientific Instruments, 2018In planar magnetic resonance imaging (MRI) systems, gradient coils are usually placed within a very limited space owing to the physical constraints of the small gap size (pole-pole) distance of the permanent magnet. Typically, the unshielded or partially shielded design scheme is adopted to generate required magnetic fields with reduced system costs ...

Mobile Cryocooler-Based SQUID NDE System Utilizing Active Magnetic Shielding
IEEE Transactions on Appiled Superconductivity, 2005A mobile cryocooler-based SQUID NDE system was developed for realization of NDE of fixed targets that can't be moved or rotated. In order to move the SQUID in an ambient field, an active magnetic shielding technique employing a compensation coil and feedback circuit including a band elimination filter was introduced in a SQUID NDE system. The HTS SQUID
