Extends from Modelica.Electrical.Analog.Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).

Information

The signal current source is a converter of real valued irradiance signal into a source current. Depending on the actual temperature the current is adjusted through a linear temperature coeffficient.

i = IRef * (irradiance / irradianceRef + alphaRef * (T_heatPort - TRef))
