Current sensor for improved functional safety

A method of manufacturing a current sensor arrangement, the method comprising:

• providing a conductor that is configured to conduct a primary current, the conductor comprising a first end and a second end oppositely arranged with respect to the first end with respect to a current flow direction of the primary current;
• forming a current impeding structure across the conductor in a bisecting manner in a first direction that is orthogonal to the current flow direction;
• forming a slit in the conductor that extends partially between the first end and the second end in the current flow direction, wherein the slit extends through the current impeding structure in the current flow direction and through the conductor in a second direction that is orthogonal to the current flow direction, wherein the slit divides the conductor into a first conductor portion and a second conductor portion both conjoined at the first end and the second end of the conductor;
• deforming the first conductor portion and the second conductor portion in opposite directions with respect to second direction, thereby defining a gap;
• and
• inserting magnetic sensor through the gap such that the first conductor portion is arranged over a first portion of the magnetic sensor and the second conductor portion is arranged under a second portion of the magnetic sensor.

A current sensor arrangement, comprising:

• a first conductor configured to conduct a first portion of a primary current along a first current path in a current flow direction;
• a second conductor configured to conduct a second portion of the primary current along a second current path in the current flow direction, wherein the first conductor and the second conductor are coupled in parallel,
• wherein the first current produces a first magnetic field as it flows through the first conductor and the second current produces a second magnetic field as it flows through the second conductor, and
• wherein the first conductor and the second conductor are separated from each other in a first direction that is orthogonal to the current flow direction, thereby defining a gap;
• and
• a magnetic sensor arranged in the gap such that the first conductor is arranged over a first portion of the magnetic sensor and the second conductor is arranged under a second portion of the magnetic sensor.
