Current limiting devices

Abstract

A current limiting device and an electrical power system including a current limiting device are provided. The current limiting device includes: a primary current path extending between a first node N1 and a second node N2 and having a primary current limiter connected therein, the primary current limiter including at least one JFET 101, 1011-N; and a secondary current path extending between the first node N1 and the second node N2 in parallel with the primary current path, the secondary current path including a Transient Voltage Suppressor (TVS). The primary current limiter is configured so that a voltage drop across the primary current limiter increases as a current flowing through the primary current path increases. When the current flowing through the primary current path passes a threshold, the voltage drop across the primary current limiter passes a breakdown voltage of the TVS.

Dependencies are inferred from the claim text.
