Abstract

In order to investigate the feasibility of dynamic loss minimization for DC-to-DC converters by control methods, transient core loss analysis for soft magnetic composite material will be
discussed in this presentation. A practical calculation model is developed to obtain the transient losses. With this model, time domain information of several trajectories can be calculated automatically. And because of simplicity of this model, it is easy to apply the calculation to finite element analysis.
