In this paper, a Boost inductor based on power factor control chip NCP1608B is designed, with an example of an output power of 120W and a prototype working in the critical working mode （CrM）. The inductance value and coil ratio are designed in detail. The specific calculation process is given, and the appropriate inductor skeleton and core are selected in detail. This paper introduces the method of inductor winding and points for attention, and gives the concrete structure diagram of the winding. Finally, the experiment is carried out and the experimental waveform and the detailed experimental parameters are given. The experimental results show that the design of the inductor is more successful.
