摘要：
Aiming at the problems of uneven population distribution and slow convergence in the calculation process of non-dominated sorting genetic algorithm II (NSGA-II), a hyperplane NSGA-II (HP-NSGA-II) was proposed. The algorithm constructed a hyperplane by connecting extreme points reflecting the edge distribution of the population, with its normal vector as the evolutionary trend, the critical layer individuals were projected on the hyperplane, which promoted the population to evolve towards the optimal solution with uniform distribution and good convergence. Dual-input dual-buck inverter (DIDBI) was a multi-objective optimization object, the switching loss, total harmonic distortion of output voltage, and volume of filter elements were regarded as optimization objectives. According to the requirements of resonant frequency, inductor current ripple, and the power factor, the constraint conditions of filter capacitance, filter inductance, and switching frequency were derived. The application situation and value of the HP-NSGA-II were compared with NSGA-II and γ-NSGA-II considering the importance of each target. An Inverter prototype was regarded as an example, the experimental research on parameters optimization design was carried out, and the results show the effectiveness and correctness of the design. © 2023 Zhejiang University.
