Sources Configuration Page

In the System Explorer window configuration tree, expand the Power Electronics Add-On custom device and select Circuit Model >> Sources to display this page.  After a model is successfully loaded in the Circuit Model Section, this page is added to the configuration tree and populated with a named list of the Source components found in the circuit model.  An incoming signal must be mapped to each Source to drive its voltage or current as it is simulated in the eHS solver.

For each Source, the following information and mapping options are available. 

Sources Settings
Type

Displays the type of source:

  • Voltage Source
The Source will output a voltage during the simulation.  The magnitude of this voltage is determined by the  magnitude of the signal mapped to the Source.
  • Current Source
The Source will output a current during the simulation.  The magnitude of this current is determined by the magnitude of the signal mapped to the Source.
Group

Filters the list of available elements to be mapped to the Source. The available options are defined by the selected Hardware Configuration, however it is typical to see the following options by default:

  • CPU (VeriStand)
VeriStand custom device channels on the CPU. If this Group is selected, the Element dropdown is populated with a single option displaying the name of the custom device channel whose value is mapped.
  • Sinewaves
Sinewave outputs of the Sinewave Generators. In the Element dropdown, select the index of the Sinewave Generator whose output signal to map.
  • Machine
Output channels of the Machine Model. In the Element dropdown, select the name of the channel to map.
  • Analog Inputs
Analog Input channels of the PXI card.  In the Element dropdown, select the index of the AI channel to map.
Element

The name or index of the signal to be mapped to the Source. The options available in this dropdown depend on the selected Group.


Sources Section Channels

After a model has been loaded in the Circuit Model Section, the Sources section of the Configuration Tree is populated with a list of channels corresponding to each Source component found in the circuit model.  If a Source is mapped to the CPU (VeriStand) Group described above, then the value of its corresponding channel defines the magnitude of the Source during the simulation.  If the CPU (VeriStand) Group is unused, then the value of the channel does not affect the circuit simulation.



Sources Description

Sources are input signals to the eHS electrical circuit model. They are either current or voltage sources whose output signals can be be driven by custom device channels, analog inputs, signal generators, and more. In the electrical circuit model, it is recommended (but not necessary) to denote the sources of the model with the UXX prefix as seen in the circuit model diagram below.  See Supported Circuit Editors for a list of supported Source components in the circuit model.
