Title:
CURRENT LIMITING CIRCUIT INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2016/190319
Kind Code:
A1
Abstract:
Provided is a current limiting circuit inductor which, despite being small in size, can provide a current limiting effect by maintaining a large inductance when an instantaneous large current flows. In particular, the current limiting circuit inductor is suitable for an electric circuit that does not require inductance during normal operation. The current limiting circuit inductor (1) is provided with a magnetic core (2) and a coil (3), and used in a current limiting circuit. The magnetic core (2) includes, at least partially, a portion comprising a soft magnetic material having low volume resistivity and high permeability. The soft magnetic material is sintered pure iron, for example.
