Seminar Description: This presentation focuses on the optimal design of inductive components through accurate modeling of magnetic, winding, and thermal losses. It begins by analyzing challenges posed by non-sinusoidal and DC-biased waveforms and demonstrates advanced modeling techniques to address them. A reluctance-based magnetic circuit model is introduced, enabling precise inductance, saturation, and stray-field calculations, even for complex air gap geometries. For core losses, a hybrid method combining loss maps with the improved Generalized Steinmetz Equation (i2GSE) is presented, capturing effects of waveform shape, DC bias, and relaxation phenomena across a wide frequency and flux density range. Winding loss modeling addresses skin and proximity effects in various conductor types, including solid, foil, and Litz wires, with analytical and FEM-based approaches. Thermal modeling then links electrical losses to component temperature rise, forming the basis for multi-objective optimization where trade-offs between efficiency, volume, and cost are considered. Throughout the talk, real-world examples and experimental validations illustrate the effectiveness of these models, culminating in guidelines for achieving compact, efficient magnetic components in modern power electronics. To enhance the learning experience, interactive elements such as live calculations, waveform analysis, and design trade-off simulations will be integrated, encouraging active participation and practical understanding.
