Dynamic nonlinear electro-thermal simulation of a thin-film thermal converter

This paper describes the electro-thermal simulation of the ac-dc transfer differences at low frequencies of a thin film thermal converter. The dynamic nonlinear model includes the temperature dependence of all material parameters, and radiation losses. It is used to optimise the performance of the device at low frequencies, where temperature oscillations are present due to the lack of integration of the oscillating Joule heat. The results of the simulation are compared with measurements against a digital method.
