N2 - This paper presents a novel short-circuit (SC) detection method. Only one centralized measurement circuit is necessary per device / inverter, with significant advantages in combination with multiphase systems. It decouples the inverse AC component of the DC-link voltage to gather information about the output current. First tests achieved a SC detection time of 5.8 µs, which is already well suitable for fast detection of a load SC. To improve the SC detection time allowing for the protection from a module-internal SC, the SC detection topology was complemented. The functionality was validated by implementation in a three-phase silicon carbide (SiC) inverter resulting in a fast SC detection and turn-off within 260 ns after SC event.
