Series circuit with Bode analysis
The frequency of the voltage source is varied by a logarithmic ramp, the supply voltage magnitude is constant.
Plot versus voltageSource.f
on a logarithmic scale in order to determine the Bode diagrams of the ratio of
the voltage of the resistor divided by the supply voltage:

arg_y

Rectifier example
This example demonstrates coupling a quasi-static circuit with a DC circuit. The QS voltage is rectified (using an ideal AC DC converter), loaded by a variable load conductor. The conversionFactor = DC voltage / AC rms voltage in this case is the root mean square of a rectified sine, i.e., 1. You may compare the quasi-static results with that of a fully transient model (using a Graetz rectifier), plotting:
It can be seen that at the DC side the current is represented by its averaged value, at the AC side by its rms value.
The quasi-static model needs a grounding at the QS side as well as the DC side, whereas the transient model may have only one ground since AC side and DC side are connected via the diodes.

Example of transformer with short circuit impedance, transmission resistances and load
This examples shows the operational behavior of transformer with short circuit impedance. The transformer is loaded with constant current magnitude of 250A but variable phase angle. The angle varies from 0 to 360 degrees within one second of simulation time.
Transformer data
V1N = 1000 V
V2N = 200 V
SN = 50 kVA
Zk = 0.72 Ohm + j*0.96 Ohm
Plot the real part of the secondary voltage idealTransformer.v2.re
on the x axis and idealTransformer.v2.im
on the y axis. The locus of this complex voltage v2
is a circle. The center of the circle is the primary supply voltage divided by the transformation ratio of n=5
. Since in this experiment the load current magnitude is constant, the voltage drop across the short circuit impedance of the transformer is constant, as well. The radius of the circle is equal to the constant magnitude of the voltage drop across the short circuit impedance.
