A rapid solution method for the thyristor electro-thermal coupling model based on the conjugate gradient method is developed to address the limitations of traditional solution techniques in terms of processing efficiency and computational cost. By optimizing the iteration process and convergence criteria, the solution efficiency and accuracy are significantly improved. A novel parameter selection strategy is introduced to automatically adjust the algorithm's iteration step size, thus accelerating the convergence speed and reducing the computational resource consumption. Compared with the traditional solution methods, the optimization approach achieves an average reduction of 10％ in solution time and an 8％ increase in solution accuracy. This progress demonstrates the effectiveness of the adaptive conjugate gradient method in the rapid solution of electro-thermal coupling models, providing an efficient and reliable computational tool for the thermal management of power electronic devices. The proposed method exhibits significant efficiency improvement and good accuracy under various test conditions, offering an innovative solution for efficiently solving the thyristor electro-thermal coupling models. This method is also of practical significance for related research in the field of power electronics.
