AI Technical Summary

Technical Problem

In high-voltage, high-series circuits, when a node is damaged or needs to be replaced, high voltage will accumulate at both ends of that node, affecting the normal operation of other nodes, reducing circuit stability, and may even cause components to burn out or explode.

Method used

The circuit employs a series node protection circuit, including fast-acting and holding high-voltage protection modules, which are connected in parallel to damaged or replaceable nodes. It utilizes a rectifier bridge, unidirectional conduction circuit, and control conduction circuit to achieve fast short circuits and continuous short circuits, protecting other devices.

Benefits of technology

When a node is damaged or replaced, the fast-acting high-voltage protection module enables a rapid short circuit, while the holding-type high-voltage protection module maintains the short circuit state, improving circuit stability and preventing damage to other components.
