VERFAHREN UND VORRICHTUNG ZUR ERFASSUNG UND/ODER REGELUNG DER TEMPERATUR ELEKTRISCHER ODER ELEKTRONISCHER BAUTEILE ODER BAUGRUPPEN

摘要

Process for finding the load and/or loadability of electrical or electronic components or groups of components which are powered from a voltage source via a power control stage and whose current-dependent calorific behaviour is known, in which: a) the heat conductivity and capacity of the components or groups of components (1) are determined; b) at least one initial value of the temperature is measured on the components or groups of components (1) or in their environment and stored; c) the current flowing through the power control stage (5) and/or the power is detected and stored; and d) the momentary temperature of the components or groups of components is calculated from the stored initial temperature and the current and/or power via an algorithm containing the heat conductivity and capacity of the components or groups of components.
