DEVICE AND METHOD FOR MEASURING OPERATING TEMPERATURES OF AN ELECTRICAL COMPONENT

摘要

An apparatus and a method for measuring operating temperatures T_j of a component, particularly transient temperatures T_j in the breakdown region of the component 2 during a breakdown operation, are provided. The component temperature T_j at a point of time t_i is ascertainable from a measurement of the breakdown voltage U_d and the breakdown current I of the component 2 at the specific point of time t_i during the breakdown operation using a measuring device, by comparing the measurement data to reference measurement data recorded in advance.
