一种基于正弦损耗的DC/DC功率变换器磁芯损耗计算方法

Traditional predicted core loss models, such as the improved Steinmetz equations, cannot show the whole changing tendency of core losses in different topologies. In this article, a core loss prediction model is presented based on sinusoidal losses. The axis of flux density is divided into a number of slice pairs in a B-Ph plane, and the hysteresis loss density is given in each slice pairs. By summ...
