DAB inductance loss calculation method based on inductive current characteristic value

The invention discloses a DAB inductance loss calculation method based on an inductive current characteristic value, and provides a current-based iGSE magnetic core loss calculation method for optimizing a traditional iGSE method for calculating magnetic core loss by calculating the inductive current characteristic value aiming at inductance loss and temperature rise of a dual-active bridge DAB circuit. And a winding loss expression based on current is given. The invention finally provides a method for calculating the total loss of the DAB inductor through the inductance current characteristic value, solves the problems that the calculation of the inductance loss is relatively long in consumed time and relatively complex, and provides an inductance loss calculation method with relatively high calculation accuracy for a DAB circuit. A designer can accurately estimate the temperature rise of the inductor in the design process, and the operation reliability of a DAB actual device is guaranteed. 本发明公开了一种基于电感电流特征值
