Analysis of orthogonal controllable extinction coil characteristic

The orthogonal extinction coil is reliable and easily controllable. Use the simulation software FEMM, the magnetic flow distribution and magnetic circuit structure are analyzed. This method is convenience to the magnetic flow analysis. With the data comparison between the magnetic flow and magnetic potential, the magnetic circuit model and magnetic potential equations can be found out. Through comparison with different magnetization curve models, this paper gives a mixed separated magnetization curve fitting method, which is very suitable to orthogonal extinction coil. And this simulation method is very important to the research on the orthogonal core. Based on this curve research, this paper also analyzes the control characteristic control ex-characteristic and adjustment characteristic.
