The invention discloses an IGBT over-temperature protection control method and device based on a state machine, and relates to the technical field of temperature control of power electronic equipment, and the method comprises the steps: dividing an IGBT into a plurality of states; monitoring the temperature of the IGBT; and according to the temperature of the IGBT, switching between different states is automatically carried out, and a corresponding power adjustment strategy is executed. According to the invention, the temperature of the IGBT can be monitored in real time, and the power output is automatically adjusted according to the temperature change, so that the stable operation and long-term reliability of equipment are ensured. The system has real-time performance, self-adaptability, reliability, flexibility and maintenance simplicity and convenience, the fault-tolerant capability of the system is enhanced by introducing a plurality of intermediate states, it is ensured that measures are taken in time when the temperature is abnormal, and work is smoothly recovered after the temperature is recovered to be normal.
