Development and applications of simulation software for integrated inductance
HU Yun-son · Journal of Magnetic Materials and Devices · 2015
Based on equivalent circuit of pot core and inductance calculation formula and magnetic field distribution of ring inductor, equivalent circuit and inductance calculation formula were given for integrated inductor. Simulation software for structure design of integrated inductor was compiled using Visual BASIC 6.0. Structure, characteristic and using method of the software were discussed. Using the software simulation for several integrated inductors was performed and on this basis inductors were prepared. It shows that deviation between the simulation and experimental results is within 10%. Use of the software can shorten the design cycle, improve the efficiency of inductor, and also can calculate the DC resistance of integrated inductor, offering a prediction for device temperature rise.
