Embodiment Construction

[0033]For purposes of illustration rather than limitation, specific details such as specific architectures, interfaces, techniques, etc. are set forth in the following description in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments that depart from these specific details. That is, those skilled in the art will be able to devise various arrangements which, although not explicitly described or illustrated herein, embody the principles of the invention and are thus included within its spirit and scope.

[0034] In some instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail. All statements herein reciting principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to encompass structural...

Abstract

A programmable fuse and fuse panel are described. Unlike conventional fuses and fuse panels, the trip values of the fuses of the panel—i.e., the current values at which the fuse trips—are field programmable. One of many advantages includes the ability to adaptively set the trip value of a fuse—depending on the operating needs of a load device—without having to physically exchange the fuse. In an embodiment, electronic fuses are used.

Description

technical field [0001] Generally, the technical field of the present disclosure relates to providing field programmable fuses and fuse panels. Some embodiments of field programmable fuses and fuse panels are based on electronic fuses. Background technique [0002] In a typical power distribution system, eg in a residential area, a fuse panel with multiple fuses is used. The trip value of each fuse is selected to protect each load device connected to the fuse. When a new load device is to be connected to the panel, select a free fuse with the appropriate trip value for the new load device. [0003] Today's fuse panels are based on a variety of different technologies, such as melting wire types, thermally activated types, and electronic types. Regardless of type, a fuse "trips" or interrupts a circuit to a load device when the current supplied to the load device exceeds a trip value. [0004] Figure 12 A conventional fuse panel 1200 including a plurality of individual fus...
