Simulation of Processes in an Electromagnetic Vibration Converter with Power Loss in the Steel Magnetic Core

Authors: Neyman L. A., Neyman V. Yu.

Annotation: The paper is focused on more accurate simulation of magnetic core eddy currents and hysteresis power loss for dynamical processes in electromagnetic vibration converters generating mechanical oscillations and other electromagnetic units of throttles and transformers applied in automatic and radioelectronic systems. The dynamic model circuit designs are analyzed with the structured modeling method using Matlab Simulink. Several models comparative analysis has been made with respect to magnetic core material saturation degree, specific iron loss non-linearity, magnetic flux non-sinusoidal change and periodical input voltage form. In spite of different approaches calculation error for all considered models is no more than 5%. It has been proved that the dynamic model is free of power loss calculation error when magnetic flux DC component occurs.
