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; ③Approximate 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.
