Method for Detection and Limitation of Short-Circuit Currents for Semiconductor Circuit Breakers in LVDC Grids Using a Pre-Saturated Inductor

This paper introduces an innovative non-destructive device designed to detect and limit short-circuit currents in LVDC grids. The proposed solution utilizes a transformer fully saturated by a permanent magnet during normal operation. When a short-circuit condition occurs, the transformer desaturates...
