Use the following formula to calculate the peak flux density: Bm=K*Ipk,Ipk stands for the peak current of input, which unit is A; ②Approximate transformer core loss(Pcv) can be calculated as following formula: Pcv=3.9E-14*f1.82*△B2.59,the unit of Pcv is W, f stands for operating frequency, which unit is kHz, △B is the operating flux density, which unit is Gauss. △B can be calculated as: △B=K*△I. 2020.01.03-A/3 Page 1 of 4 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation PDF
