Solder delamination is one of the main failure modes of IGBT module. When the severity of the failure mode is different, the temperature character of IGBT is also different. This paper presents a methodology based on 3D thermal-electro coupling finite elements modeling intended to analyze the relation between the failure degree and the temperature, The results suggest when the area of solder delamination...
The paper introduces the random factor in Particle Swarm Optimization. Comparing with inertia weight, the particle's velocity is determined by previous velocity, own experience, public knowledge and random behavior. The random operator is similar with the mutation operator in the Genetic Algorithms. Simulation results show that the method introducing the random factor is better than inertia weight...
Analyzing the distance between the location and the new location, we conclude inertia weight method which linearly decreases from 0.9 to 0.4 has the powerful local search ability on Schafferpsilas F6 function. In order to improve the balance between local and global search ability, the novel adaptive PSO algorithm which evaluates a reset function to control the inertia weight value is proposed. Once...
