Model Modelica.​Electrical.​Analog.​Basic.​HeatingResistor
Temperature dependent electrical resistor

Information

This is a model for an electrical resistor where the generated heat is dissipated to the environment via connector heatPort and where the resistance R is temperature dependent according to the following equation:

    R = R_ref*(1 + alpha*(heatPort.T - T_ref))

alpha is the temperature coefficient of resistance, which is often abbreviated as TCR. In resistor catalogues, it is usually defined as X [ppm/K] (parts per million, similarly to percentage) meaning X*1e-6 [1/K]. Resistors are available for 1 .. 7000 ppm/K, i.e., alpha = 1e-6 .. 7e-3 1/K;

Via parameter useHeatPort the heatPort connector can be enabled and disabled (default = enabled). If it is disabled, the generated heat is transported implicitly to an internal temperature source with a fixed temperature of T_ref.

If the heatPort connector is enabled, it must be connected.

Model Modelica.​Electrical.​Analog.​Basic.​M_Transformer
Generic transformer with free number of inductors

Information

The model M_Transformer is a model of a transformer with the possibility to choose the number of inductors. Inside the model, an inductance matrix is built based on the inductance of the inductors and the coupling inductances between the inductors given as a parameter vector from the user of the model.

An example shows that approach:
The user chooses a model with three inductors, that means the parameter N has to be 3. Then he has to specify the inductances of the three inductors and the three coupling inductances. The coupling inductances are no real existing devices, but effects that occur between two inductors. The inductances (main diagonal of the inductance matrix) and the coupling inductances have to be specified in the parameter vector L. The length dimL of the parameter vector is calculated as follows: dimL=(N*(N+1))/2

The following example shows how the parameter vector is used to fill in the inductance matrix. To specify the inductance matrix of a three inductances transformer (N=3):

L_m

the user has to allocate the parameter vector L[6] , since Nv=(N*(N+1))/2=(3*(3+1))/2=6. The parameter vector must be filled like this: L=[1,0.1,0.2,2,0.3,3] .

Inside the model, two loops are used to fill the inductance matrix to guarantee that it is filled in a symmetric way.

Model Modelica.​Electrical.​Analog.​Basic.​OpAmpDetailed
Detailed model of an operational amplifier

Information

The OpAmpDetailed model is a general operational amplifier model. The emphasis is on separating each important data sheet parameter into a sub-circuit independent of the other parameters. The model is broken down into five functional stages input, frequency response, gain, slew rate and an output stage. Each stage contains data sheet parameters to be modeled. This partitioning and the modelling of the separate submodels are based on the description in [CP92].

Using [CP92] Joachim Haase (Fraunhofer Institute for Integrated Circuits, Design Automation Division) transferred 2001 operational amplifier models into VHDL-AMS. Now one of these models, the model "amp(macro)" was transferred into Modelica.

Model Modelica.​Electrical.​Analog.​Basic.​VariableCapacitor
Ideal linear electrical capacitor with variable capacitance

Information

The linear capacitor connects the branch voltage v with the branch current i by
i = dQ/dt with Q = C * v.
The capacitance C is given as input signal. It is required that C ≥ 0, otherwise an assertion is raised. To avoid a variable index system, C = Cmin, if 0 ≤ C < Cmin, where Cmin is a parameter with default value Modelica.Constants.eps.


Besides the Cmin parameter the capacitor model has got the two parameters IC and UIC that belong together. With the IC parameter the user can specify an initial value of the voltage over the capacitor, which is defined from positive pin p to negative pin n (v=p.v - n.v).


Hence the capacitor is charged at the beginning of the simulation. The other parameter UIC is of type Boolean. If UIC is true, the simulation tool uses


the IC value at the initial calculation by adding the equation v= IC. If UIC is false, the IC value can be used (but it does not need to!) to calculate the initial values in order to simplify the numerical algorithms of initial calculation.

Information

The linear inductor connects the branch voltage v with the branch current i by

The inductance L is as input signal. It is required that L ≥ 0, otherwise an assertion is raised. To avoid a variable index system, L = Lmin, if 0 ≤ L < Lmin, where Lmin is a parameter with default value Modelica.Constants.eps.

Besides the Lmin parameter the inductor model has got the two parameters IC and UIC that belong together. With the IC parameter the user can specify an initial value of the current that flows through the inductor.


Hence the inductor has an initial current at the beginning of the simulation. The other parameter UIC is of type Boolean. If UIC is true, the simulation tool uses
