NOVETROL
Within the NOVETROL project, a novel, fast, passive, and self-regulating current limiter for DC networks is being investigated. This device is based on the extraordinary magnetoresistance effect occurring in semiconductors with very high charge carrier mobility. The component functions similarly to a thermistor: instead of increasing its resistance with rising temperature, the resistance increases in response to the magnetic field generated by the fault current that the system is intended to limit….
