Abstract

A frequency adaptive BBMC main circuit parameter optimization method is proposed. The optimization objectives and optimization goal are determined, and the relevant mathematical model and its multi-objective optimization fitness function are established. On this basis, the optimization of the main circuit parameters is proposed by using the salp swarm optimization algorithm, and then the optimal main circuit parameters under different rated output frequencies are studied by numerical fitting method. The function relationship describing their variation rules is established. Finally, the effect iveness is verified by constructing the simulation model and the hardware experimental device.
