Behavioral modeling methodology applied to power systems thermal analysis

New modeling methodologies are being applied in power complex systems to study all the problems that are found. One of these problems is power consumption and thermal management, considering the quantity and distribution that a system could tolerate. In this paper we have started studying the most important devices included in the system to finally consider the complete circuit. The applied methodology is based on the use of the VHDL-AMS language (IEEE1076.1-1999 standard). It will allow the electro-thermal interaction of the modeled system. We have applied this methodology on DC/DC Converters, which is a commercial product that presents high power consumption.
