摘要: The compound active clamp zero voltage soft switching (CACZVS) three-phase power factor correction (PFC) converter has many advantages, such as high efficiency, factor, bi-directional energy flow, and of all the switches. Triple closed-loop PI controllers are used for converter. control objectives include a fast transient response, accuracy, unity factor. There six parameters that need to be tuned in order obtain multi-objective optimization. However, mutually dependent objectives. This is beyond scope traditional experience based tuning method. In this paper, an improved chaotic particle swarm optimization (CPSO) method been proposed optimize controller parameters. method, multi-dimensional sequences generated by spatiotemporal chaos map initial particles get better distribution avoid local minimums. Pareto optimal solutions also weight selection difficulty multi-objectives. Simulation experiment results show effectiveness superiority
