Coreless current sensor for high current power module

A power module configured to supply power to a load, comprising:

• a current generator configured to generate a plurality of phase currents;
• a plurality of current rails each configured to receive a respective phase current of the plurality of phase currents and output the respective phase current from the power module, wherein each of the plurality of current rails includes a first opening formed therethrough, and the plurality of phase currents, while flowing along a respective current rail of the plurality of current rails in an output direction, produces a respective magnetic field;
• and
• a plurality of magnetic sensors, wherein each one of the plurality of magnetic sensors is inserted into the first opening of a different one of the plurality of current rails such that each magnetic sensor is inserted between internal sidewalls of a current rail that form the first opening into which it is inserted, and each magnetic sensor is configured to generate a differential sensor signal based on the respective magnetic field impinging thereon such that a plurality of differential sensor signals are generated,
• wherein the current generator is configured to regulate the plurality of phase currents based on the plurality of differential sensor signals received from the plurality of magnetic sensors.
