The simple diode is an electrical one port, where a heat port is added, which is defined in the Modelica.Thermal library. It consists of the diode itself and a parallel ohmic resistance R. If useTemperatureDependency is set to true, the diode formula is:
v/N/vt_t
i = Ids (e - 1)
vt_t = k*temp/q
If useTemperatureDependency is set to false, the diode formula utilizes the voltage equivalent of the temperature, i.e.,
v/Vt
i = Ids (e - 1).
If the exponent v/N/vt_t or v/Vt, respectively, reaches the limit Maxexp, the diode characteristic is linearly continued to avoid overflow.
The thermal power is calculated by i*v.
