modelSolarPyramidDCConverter
Solar pyramid with DC/DC converters
Extends from Modelica.Thermal.HeatTransfer.Interfaces.PartialConditionalHeatPort (Partial model to include a conditional HeatPort in order to dissipate losses, used for graphical modeling, i.e., for building models by drag-and-drop), Modelica.Electrical.PowerConverters.Interfaces.ACDC.DCtwoPin (Positive and negative DC pins).
Information
Model of a symmetric solar pyramid as used for a
Mars rover
prototype. This model consists of four symmetrical photovoltaic panels.
The center position of can be moved vertically, such that the four panels are moved altogether.
The angle of inclination of each panel, gamma, is an input to this model.
The second input is the azimuth of one of the fore panels. The remaining three panels are
displaced by 90 degrees, each.
This model includes four DC/DC converters
