Abstract:
A power electronics system includes: a power semiconductor module with opposite first and second sides and lateral sides connecting the first and second sides. The power semiconductor module includes: at least one power semiconductor die forming at least one part of a half bridge circuit, an encapsulation encapsulating the power semiconductor die, and an external contact configured as a current contact of the half bridge circuit and exposed from the encapsulation at a lateral side of the power semiconductor module. A driver module arranged over the first side of the power semiconductor module is configured to control the half bridge circuit. A differential Hall sensor arranged over the external contact is configured to detect a current in the external contact. The driver module is configured to modify a control pattern of the half bridge circuit based on a current value detected by the differential Hall sensor.
