THE TRANSACTIONS OF KOREAN INSTITUTE OF POWER ELECTRONICS(2023)
摘要
This paper proposed an inductor optimal design algorithm in terms of volume and loss when designing a boost inductor for PFC. Inductors occupy a large volume in the converter, and reducing the volume of the inductor is necessary to improve power density. However, a smaller volume corresponds to a greater maximum flux density, thereby leading to higher losses. The Pareto optimization technique was applied to design an inductor optimized for volume and loss, which show a trade-off relationship. This paper also proposed an algorithm for efficiently generating a Pareto set of volume and loss optimization problems of inductors. This algorithm was applied to the boost inductor of the interleaved totem-pole bridgeless PFC converter, and its effectiveness was verified through experiments.
