Energy based fuse modeling and simulation

A procedure of the energy based fuse model development is presented in the paper. A fuse model, including both pre-arcing and arcing characteristics from any given time-current characteristic curve, was developed. The developed fuse model was based on energy through fuses. Curve fitting technique can determine fuse melting time accurately. The fuse model was tested and validated via simulations. The model was built in Matlab/Simulink and the parameters of the fuse can be input from a user interface.
