EMC simulations are an indispensable tool to analyze EMC noise propagation in power converters and to assess the best filtering options. In this paper, we first show how to set up EMC simulations of power converters and then we demonstrate their use

Engineered, highly-controllable quantum systems hold promise as simulators of emergent physics beyond the capabilities of classical computers. An important problem in many-body physics is itinerant magnetism, which originates purely from long-range i

This paper reports on a strongly physics-based minimal circuit model for polycrystalline cores, such as ferrites, including dimensional resonance (DR). The models and main properties of DR and hysteresis are recalled, a circuit model is described tha

A model of magnetic components is presented which includes saturation and static hysteresis and covers a wide frequency range. A dedicated setup measures the B(H)-curves for extraction of the model parameters and for model validation. The magnetic mo

Conducted emission noise levels for power drive systems are limited by the EN 61800-3 standard which also specifies the configuration of the test setup. Long cable and wiring configuration are not strictly specified in the relevant norms but can have

In conventional EMC-filter design for power converters, common mode chokes are designed with sufficient margin to saturation. However, for chokes based on toroidal ferrite cores, nonlinear effects like saturation and hysteresis can improve the filter
