摘要

Abstract

In order to solve the problem of system failure of insulated gate bipolar transistor (IGBT) due to overheating

an intelligent monitoring and adaptive protection system with real-time feedback from cloud is proposed in this paper. The system hardware integrates high-precision temperature sensor

STM32 microcontroller and ESP8266 communication module

optimizes overtemperature protection threshold through Proteus simulation

develops embedded program to realize real-time temperature data acquisition (error <±0.5℃)

fast overtemperature protection (response time <10ms) and cloud data transmission (packet loss rate <0.1%). Based on the historical data

an adaptive threshold model is constructed to dynamically adjust the protection strategy to cope with the complex electromagnetic environment. The experiment shows that the system maintains high stability in both hardware test and simulation

and the IGBT failure rate is significantly reduced. The solution realizes the intelligent closed-loop control of thermal management through the local-cloud collaboration mechanism

provides innovative solutions for smart grid and industrial equipment

and promotes the digital and adaptive upgrade of power electronics systems. Future research will strengthen the robustness of algorithms under extreme conditions and explore edge computing fusion architectures to improve real-time decision making capabilities.
