Abstract

Electromagnetic fields Inverters Linear systems Magnetic analysis Magnetic fields Magnetic flux Magnetic materials Nonlinear systems Saturation magnetization Voltage
For linear systems excited with sinusoidal constraints, an exact dynamical modelling can be performed with a phasor (complex number) approach. For nonlinear systems (exhibiting saturation, hysteresis and higher harmonics), a time stepping model is very time consuming. A method to model such nonlinear systems with an approximated phasor approach is presented. Determination of equivalent material characteristics is discussed and applications are given.
