Embodiment Construction

[0032] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Different from the conventional solid-state power distribution technology, the core components of the solid-state power distribution technology involved in the present invention have configurable functions, including the advantages of configurable key characteristic parameters, reconfigurable functions, and programmable protection characteristics, which can avoid traditional solid-state power distribution. The power distribution mode is single, the function is limited, and the application range is narrow; at the same time, its control part adopts the FPGA hardware circuit design method, which avoids the crash, program runaway, and program failure that may be caused by software design (such as single-chip microcomputer, DSP, etc.). The shortcomings of low reliability such as operating errors and weak anti-interference greatly impr...

Abstract

The invention relates to a brand-new FPGA-based configurable digital solid-state power distribution system, which has the advantages of configurable key characteristic parameters and programmable protection characteristics, avoids the influence on the application range of application due to the limitation of load characteristics on power distribution caused by fixed key parameters, fixed protection characteristics and the like, has a reconfigurable function and can realize selection of protection characteristics, so that different solid-state electronic switch types are reconstructed, and application working condition limitation and application range limitation caused by a single solid-state power distribution mode are avoided.

Description

technical field [0001] The invention relates to FPGA-based configurable digital solid-state power distribution technology and belongs to the technical field of power electronics. Background technique [0002] Solid-state power distribution uses solid-state electronic switches as the core components, and solid-state electronic switches use power tubes as the core control switches. Long, high reliability and other advantages. Solid-state electronic switches include solid-state electronic switches with protection functions, such as based on I 2 Solid-state power controller products with t function and short-circuit immediate trip function, solid-state current-limiting switches based on constant-current current-limiting function, and other products; and solid-state electronic switches without protection functions, such as solid-state relays. However, the traditional solid-state power distribution technology has the disadvantages of single mode, limited functions, and narrow ap...
