Magnetic Components Precise Modeling for Power Converters

Résumé

In power electronics applications, magnetic components are often subjected to non-sinusoidal waveforms, variable frequencies and DC bias conditions. These operating conditions generate different losses compared to sinusoidal losses provided by manufacturers. Since virtual prototyping is used to predict and improve system's behavior before realization, losses and behavior prediction of components is required. Circuit simulators and their compatible components models are required. This work is summarized by proposing non-linear dynamic model of magnetic components for use in circuit simulators. It includes the material's nonlinear hysteresis behavior with accurate winding and core modeling. The magnetic component model is implemented in circuit simulation software " Simplorer " using VHDL-AMS modeling language. Waveforms and losses of a powder core inductor in a buck converter application are simulated and compared to measured ones.
