This paper details the creation of a high-performance, highly reliable electronic system made entirely from domestically sourced components. Taking into account the operational features and technical specifications of each module circuit, the system integrates a power circuit design, sampling circuit scheme, protection module design, and drive scheme—all using locally produced parts without sacrificing technical standards. Moreover, to enable rapid short-circuit protection for the SiC MOSFET module, a new short-circuit protection approach based on instantaneous energy is introduced. The developed electronic system has successfully undergone dual-pulse testing and bench evaluations, fully confirming its functionality and performance. The study demonstrates that a fully domestically manufactured electronic system is practical, safe, and dependable, providing a feasible solution for the complete localization of power generation systems. Additionally, it offers crucial technical support for the reliable protection and broad implementation of domestically produced high-voltage, high-current SiC MOSFET power modules.
