  title={Large-signal Simulation Model for Ptc Thermistor},
  author={Timo Veijola},
A compact electrothermal simulation model for a semiconductor thermistor with positive temperature coeecient (PTC) is presented. The model presented is phenomenological, but it is based on physical models published by Heywang (1961,1964), Mallick and Emtage (1968), and Zhang and Cao (1996). With this dynamic, non-linear electrical-equivalent circuit model, combined electrical and thermal behaviour of PTCs can be analyzed in the frequency and time domains with a circuit simulation program.
