Control Method for Electric Fuses with Controllable Fusing

In order to improve the electric fuse features, a new concept of controllable fusing has been patented. The controllable fusing means the possibility of fuse to operate at certain time moments when an external command is activated. The experimental set up has been built on the basis of a virtual instrument application. Using this instrument, there is the possibility to acquire the current waveform which flows through the fuse and set the current threshold when a command signal is provided in order to blow the fuse on the basis of controllable fusing effect. Actually, there is implemented the time-current characteristic of the new fuse, and depending on the application the moment of circuit interruption can be delayed. It results an adjusted new time-current characteristic for the fuse.
