Description
Summary:In order to calculate the inductance of transformer simulation model, this paper presents a new calculation method based on transformer magnetic circuit. This method calculates the mutual inductance and leakage inductance respectively. When calculating the leakage inductance, the effect of vertical leakage flux and horizontal leakage flux have been considered, which makes the calculating result are more correct. In order to prove the validity of this method, the data of simulation test and dynamic analog test have been compared. The results have proved that the method of magnetic circuit calculation is accurate
