Abstract

Three phase LLC resonant converter has the advantages of high conversion efficiency and low switching voltage stress. However, its three inductors show independent characteristics, increasing the volume and cost. The magnetic integration technology is thus introduced for the three phase LLC resonant converter design to reduce the volume of magnetic core and improve the utilization of magnetic core. Firstly, the ANSYS simulation model is established, and the magnetic integration scheme of the three inductors is determined by analyzing the magnetic circuit distribution of the inductor. Finally, the magnetic integration scheme of the inductor is designed to offset magnetic flux of the common magnetic circuit partially. The simulation and experimental results show that the designed inductive magnetic integration method can reduce the inductance volume by 13% and effectively improve the power density of the resonant converter.
