A system is provided for overcurrent protection of a multi-phase trans-inductance voltage regulator. The multi-phase trans-inductance voltage regulator comprises a plurality of transformers, each transformer comprising a primary inductor and a secondary inductor. The primary inductor of each transformer is provided between a respective input node and a common output node, and the secondary inductors of the plurality of transformers are connected in series. Each input node is connected to a respective one of a plurality of phase inputs. The system includes a first sensor arrangement configured to measure a current flowing through the secondary inductors. The system also includes a controller configured to generate an overcurrent fault signal based at least in part on the measured current flowing through the secondary inductors. Also disclosed is a multi-phase trans-inductance voltage regulator including the system, and an associated controller and method for overcurrent protection of a multi-phase trans-inductance voltage regulator.
