For a dynamic loss minimization control for DC-to-DC converters, a transient loss analysis of a multiple-gap inductor designed for the 2010 Prius is presented in this paper. A transient core loss calculation algorithm based on an equivalent elliptical loop (EEL) is used for the time domain loss analysis. The algorithm is combined with finite element analysis (FEA), and the core loss and copper loss...
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 is presented in this paper. A practical calculation model based on equivalent elliptical loop (EEL) model is developed to obtain the transient losses, and the algorithm is modified to adapt to non-sinusoidal waveforms by...
This paper presents a dynamic core loss model for active loss control of permanent magnet synchronous machines. Deadbeat-direct torque and flux control (DB-DTFC) enables direct control of torque and stator flux linkage over each switching period. Total machine loss can be minimized by selecting the optimal flux level in every sampled time instant. Reliable models for dynamic copper and core loss are...
