Abstract: A current sensor assembly including: a plurality of electrical conductor portions for conducting electrical currents; each conductor portion having two interconnection portions disposed between two main body portions, the interconnection portions extending in a first direction and spaced apart so to form an opening between them; one or more printed circuit boards comprising at least two lips or protrusions accommodating at least two sensor devices; each sensor device being arranged at least partially inside one opening, and configured for measuring at least two magnetic field components oriented in a direction perpendicular to the semiconductor substrate at two sensor locations spaced apart in the second direction. A printed circuit board having at least one cut-out and lip and magnetic sensor device. A power invertor includes such current sensor assembly and/or such a PCB.
