HeatingDiode

Simple diode with heating port

    HeatingDiode

Library

Modelica/Electrical/Analog/Semiconductors

Description

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 an parallel ohmic resistance R. The diode formula is:

                v/vt_t
  i  =  ids ( e        - 1).

where vt_t depends on the temperature of the heat port:
  vt_t = k*temp/q

If the exponent v/vt_t reaches the limit maxex, the diode characteristic is linearly continued to avoid overflow.
The thermal power is calculated by i*v.
