Method for acquiring temperature of electrical/ electronic component, and circuit

The invention relates to a method for acquiring the temperature of at least one electrical/electronic heat-generating component of a circuit of in particular a controller or power electronic device. The circuit has at least one temperature sensor and one or more elements arranged between the temperature sensor and the component to transfer the heat from the component to the temperature sensor. Themethod comprises the following steps: a) detecting a temperature (T3) by means of the temperature sensor; b) acquiring the power loss (Pv) of the component; c) acquiring the heat capacity (C) of eachelement arranged between the component and the temperature sensor; d) acquiring heat transfer resistance (R) which act between the adjacent elements and between the component and the temperature sensor, and e) determining the temperature of the component as a function of the acquired power loss, heat transfer resistances (R), heat capacities (C) and the detected temperature (T3). 本发明涉及一种用于获取尤其控制器或者功率电子器件的电路的、至少一个电气的/电子的产生
