N2 - In recent years, the power supply of the data center is increasing day by day. The new power supply architecture uses 48V bus to supply power to the subsequent VRM, so as to reduce I2R loss. Because of its soft switching characteristics, LLC resonant converter can meet the requirements of high power density and high efficiency, and is used in isolated DC-DC converter. In this paper, a magnetic integrated transformer is proposed to reduce winding loss and core loss. The windings and magnetic cores are optimized in local detail. A 1500W module was made in the experiment, achieving 97.8% peak efficiency and 97.6% efficiency at full load.
