For emerging consumer applications in navigation and motion sensing [1], it is crucial to design a tri-axis magnetic field sensor compatible with planar microfabrication technologies for mass production.
The rapid development of large scale power system and the implementation of dispersed generation have led to the increasing level of fault current which may be over the breakers' operating limit threatening the safety of power system.
The saturable magnetically controlled reactor (MCR) applying dc control currents has been widely used in the voltage regulation and reactive power compensation in the electric power system [1].
Virtual air gap controlled reactor (VGR) is an electrical device based on the working principle of the saturation in the iron cores [1]. The magnetic permeability of the iron cores in the VGR can be changed smoothly by regulating the direct current in the exciting windings. The higher the magnetic permeability of the iron cores, the greater the inductance of the VGR is, and vice versa. Since the advantage...
In order to flexibly compensate reactive power, it is necessary to develop a controllable reactor in long distance and ultrahigh voltage system. A leakage flux-controlled reactor (LFCR) is developed in this paper. The operation principles of LFCR are discussed in detail, and a 380 V single-phase LFCR prototype is developed. Relevant experiments have been done to test its performance. The results of...
