Abstract

See full text

A device is provided for the temperature measurement and thermal protection of an object and more particularly of an electronic 'solid state' circuit, using an analog network representative of a thermal model of the circuit to be protected. It comprises, on the one hand, an initialization device for, at the time of switching on, positioning the state of the thermal model at an operating point representative of the real temperature of the object to be protected and, on the other hand, elements isolating the analog network thus allowing it to be representative of the real thermal state of the circuit to be protected, whatever the state of the circuits internal to said device. The device is appropriate for thermal protection of an electronic power controller.
