Fremgangsmåde til overvågning af effekthalvlederkomponenter

摘要

The circuit arrangement includes at least two electrically separated groups of contact areas (10) with the same functionality. The contact areas are provided on a power semiconductor. Each electrically separated group of contact areas are connected with the neutral point of a star connection (18) via an active and/or a passive component (17). All electrically separated groups of contact areas are connected with at least a further contact area (16) provided outside the power semiconductor. An Independent claim is also provided for a method for monitoring the circuit arrangement.
