Solid state power controller

Abstract

The invention relates to a solid-state power controller, which comprises a hard wire configuration unit (1), a bus unit (2), a configuration circuit (3) and an algorithm control circuit (4), and is characterized in that the hard wire configuration unit (1) and the bus unit (2) are respectively used for receiving an external hard wire configuration signal and an external bus configuration signal; and the signal is transmitted to the configuration circuit (3) and the algorithm control circuit (4) so as to configure the working mode and parameters of the solid-state power controller. According to the solid-state power controller, the defects that online reconstruction cannot be achieved, the working mode, the initial state and the protection characteristic cannot be adjusted, and the application range is greatly limited due to high customization and specificity in the prior art can be overcome, and meanwhile the purpose of microminiaturization integration can be achieved.

Description

technical field [0001] The present invention relates to a solid state power controller. Background technique [0002] The solid-state power controller is a kind of solid-state electronic switch. Generally, the power tube is used as the core control switch. Because of its advantages of no contact, no arc, no noise, fast response, small electromagnetic interference, long life and high reliability, it is favored Widely used in various fields. Solid state power controllers are usually based on I 2 t inverse time protection curve to achieve overcurrent protection for power distribution channels. The solid-state power controllers in the prior art can be divided into two categories according to whether they have reconfigurable features such as programmable and configurable. The first category is non-reconfigurable solid-state power controllers. , protection features, etc. are solidified by the hardware before the design is finalized, and are not adjustable, so they do not have r...

Problems solved by technology

[0003] From the point of view of implementation, the main implementation methods of these two types of products can be subdivided into two types. The first one is implemented by discrete devices. Due to the large number of components and components, it is difficult to achieve high-density integration and miniaturization; the second one uses The chip-based route integrates functions into a chip to form a dedicated integrated controller. However, the existing second type of dedicated controller has relatively fixed functions and is not configurable. Therefore, once the design is finalized, the product features cannot be reconfigured online. , that is, the working mode, initial state, and protection characteristics are not adjustable, and the customization and specificity are high, resulting in a greatly limited application range
