DESAT Protection Circuit with Adaptive Threshold and Blanking Control

The patent implements software-based parameter adjustment mechanisms that allow the DESAT protective circuit configuration to be modified through code rather than physical component exchange. The control unit can load different configuration parameters (such as threshold voltages, blanking times, and current limits) from storage, enabling the same hardware circuit to adapt to various power devices and substrates without requiring disassembly or component replacement. This resolves the contradiction by maintaining circuit adaptability while eliminating the time-consuming physical adjustment process.

The patent replaces the mechanical process of physically exchanging resistors and capacitors with an electronic/software-based configuration system. The control unit communicates with the DESAT protective circuit through electrical signals, allowing configuration changes to be made via software commands rather than manual component handling. This substitution dramatically improves ease of operation while maintaining the ability to adapt the circuit to different power devices and substrates through parameter modification.

The patent implements a universal control unit that can manage multiple DESAT protective circuits with different configuration requirements. The control unit includes a storage module that can hold various configuration sets for different power devices and substrates, and a parameter adjustment module that can switch between these configurations as needed. This allows a single circuit design to serve multiple functions and adapt to various applications without requiring separate dedicated circuits for each device type, thereby maintaining structural simplicity while achieving broad adaptability.
