Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network

Information

This partial model provides a conditional heating port for the connection to a thermal network.

If this model is used, the loss power has to be provided by an equation in the model which inherits from ConditionalHeatingPort model (lossPower = ...). As device temperature T_heatPort can be used to describe the influence of the device temperature on the model behaviour.

Modelica.Magnetic.FluxTubes.Interfaces.PartialGenericHysteresisTellinen Modelica.Magnetic.FluxTubes.Interfaces.PartialGenericHysteresisTellinen

Partial Tellinen hysteresis model

Information

A reluctance with the Tellinen hysteresis model. The major hysteresis loop is defined by the hyperbolic tangent function.

The Tellinen Hysteresis Model

The Tellinen hysteresis model is a simple model to describe the magnetic hysteresis behavior of ferromagnetic materials. It only uses the rising (hystR) and falling (hystF) branch of the major hysteresis loop and their derivatives der(hystR) and der(hystF). See Fig. 1 and the following equations for a short description of the Tellinen hysteresis model.

diffHyst = hystF - hystR;
dhR = hystF - b;
dhF = b - hystR;

if the magnetic field intensity increases (der(h)>0)

der(b) = dhR/diffHyst * der(hystR);

if the magnetic field intensity decreases (der(h)<0)

der(b) = dhF/diffHyst * der(hystF);
