Abstract

An inrush current limiter for electronic fuses detects the type of load connected to the electronic fuse at ignition. By detecting the type of load, the limiter prevents a large peak current from flowing through the fuse. When a short circuit occurs, the limiter ensures that the electronic fuse only operates once in linear mode.

Description

technical field [0001] Various embodiments of the invention generally relate to limiting inrush current. Background technique [0002] Fuses are commonly used to protect wires and electrical equipment from excessive current flow. Fuses are especially required for vehicles, such as automobiles. In various automobiles and trucks, blade type, Bosch type, Lucas type, glass tube type, and limiter type fuses have been used. [0003] When such fuses operate, they may "trip" when a hazardous situation occurs. After repeated operations, the fuse may "blow", which causes the operation to fail. Therefore, such fuses may have to be replaced periodically, as a "blown fuse" will cause some components in the vehicle to no longer function properly. Contents of the invention [0004] Various embodiments are briefly summarized below. Some simplifications and omissions may be made in the following summary of the invention, the purpose of which is to emphasize and introduce some aspects ...
