With the rapid development of science and technology, the demands for miniaturization, integration and high frequency of the electromagnetic devices were steadily increased. The integrated inductor is an important passive component for RF devices such as power transformers, amplifiers and oscillators. However, the performance of on-chip integrated inductors was poor when operating in GHz band. It...
The DC-biased magnetization is often occurring in electromagnetic devices running process, such as the power transformer, iron core reactor and other high-voltage electrical equipment [1]. However, There are three main kinds of traditional offline measuring methods under dc-biased magnetization: Epstein Frame, Ring Test and Single Sheet Measurement. The important limitation of the three aforementioned...
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...
