BOOST Inductor Optimizing Design Based on Finite Element Simulation

As the role of energy storage and filtering in DC/DC converter, the inductor is widely applied in switching power supply designs. BOOST inductor affects the input/output ripple voltage and current. Improper parameter design can cause inductor saturation easily, so the inductor design is the emphasis and difficulty in the Boost circuit design. In this paper, combining the traditional parameter calculation and finite element simulation, a design process of the BOOST inductor is given in detail, and the correctness of the design was validated by the experiments. It provides a more convenient and effective design approach of Boost inductor design.
