“…The measurements are performed for two cases: "2-Gap" and "4-Gap" states shown schematically in the figure . For the same G L , the length of one gap in the 2-Gap state is twice that in the 4-Gap state. The black and white circles indicate the measured P Gap values of 2-Gap and 4-Gap states, respectively, and the solid curves are fitted by simulating the distributions of B with an FEM simulator and calculating the P Gap values from (6) with A e = 5.86 × 10 7 . The P Gap values of the reactors used in the following sections are calculated using this result.…”

“…Digital Object Identifier 10.1109/TPEL.2013.2279256 To design reactors using low-loss amorphous cores, various approaches have been reported, such as optimizations of core shapes based on magnetic simulations [6], [7] and assumptions of nonlinear equivalent magnetic circuits for cores near a magnetically saturated state [8]. However, even now, most of the design stages of the reactors are the same as those of conventional silicon-steel cores as shown in Fig.…”

We have developed a loss estimation method that is applicable to three-phase ac reactors using amorphous cores in a 400-kVA UPS. The method is based on measured the B-H curves and iron losses of the cores, modeled with magnetic simulations of a finite-element method considering the directions of the amorphous ribbon planes. The reactors are formed from wound cores. Two types of magnetic legs are proposed: structure A, toroidalshaped with slits, and structure B, sector prism-shaped cut from a wound core. Their unit volumes are shrunk by 9% and 19%, respectively, compared with that of a conventional silicon-steel core reactor. Both reactors have about half the total losses of the conventional silicon-steel core reactor, resulting in increased UPS efficiencies of up to 0.55%. The calculated iron losses at the pulse width modulation (PWM) carrier frequencies agree with measured losses within 10%. The accuracy of the loss estimation method for PWM-induced reactors is discussed. The method is confirmed to enable accurate design of a reactor for filtering in a high-efficiency inverter system.

“…In the choice of core structure type and geometry size, the magnetic properties should be made full use of. At the same time, geometry size is smallest and weight is lightest in the premise of technical requirements [5]. Considering above all, the core structure of magnetic valve controllable reactor is as follows: In Figure 1, core column on left and right sides have the same two small sections, and every core column is winded by 3 coils of whose turns are 247.…”

The core cross section area of magnetic valve controllable reactor has a reduced section. By changing the saturation degree of the cross section area, the capacity of the reactor can be changed. In this paper, focusing on a new type of magnetic valve controllable reactor prototype, the precise 2-D field-circuit coupling model of the prototype is established in the finite element analysis software ANSYS. Based on this model, the magnetic state within the core is studied under the combined effects of AC and DC. The theoretical analyses and simulation results show that the analyzed 2-D field-circuit coupling model can reflects the actual reactor transient electromagnetic process accurately.

Magnetic-valve controllable reactor (MCR) has been widely applied in many kinds of industries, such as power systems and ferrous metallurgy. As electrical equipment, MCR can adjust its reactance smoothly and continuously, which has advantages like low dissipation and maintenance costs, high reliability. In this paper, a precise 2-D field-circuit coupling model of MCR is established by the finite element analysis software-ANSYS, and then the analysis of the harmonic characteristics of this model is presented in detail. Compared with the conventional numeric method, the proposed method could obtain more practical and accurate results and also has the ability to analyze electromagnetic field. Meanwhile, an experimental platform of a 2200 VA/380 V MCR is built. This paper provides detailed harmonic characteristics analysis of simulation and experiment. The simulation and experimental results verify that the proposed method is more accurate than using conventional ways. Index Terms-Finite element analysis (FEA), harmonic analysis, magnetic-valve controllable reactor (MCR).
