开关电源变压器磁芯多是在低磁场下使用的软磁材料,它有较高磁导率,低的矫顽力,高的电阻率。磁导率高,在一定线圈匝数时,通过不大的激磁电流就能承受较高的外加电压,因此,在输出一定功率要求下,可减轻磁芯体积。-Switching power transformer cores are mostly used in low magnetic field of soft magnetic materials, it has a higher permeability, low coercivity, high resistivity. Permeability rate, a certain number of turns, through the small magnetizing current can withstand high voltage, therefore, a certain power in the output request, reduce the volume of the core.
