摘　　要：船载脉冲功率系统(PPS)由DC/DC变换器及脉冲负载构成,其功率冲击特性受变换器参数影响。考虑变换器与脉冲负载的不同开关频率特性,提出了PPS动态过程建模及其变换器参数优化方法。分析了不同开关状态组合方式下的PPS动态过程,提出了PPS多动态过程变换器开关通断时间等效计算方法,建立了含有变换器电感与电容参数的PPS全过程状态方程。以优化PPS的电压、电流外特性为目标,建立DC/DC变换器电感与电容的优化模型,并利用非支配排序遗传算法(NSGA-Ⅱ)求解。分别在MATLAB/Simulink、RT-LAB中建立含PPS的船舶综合电力系统,验证了所提建模与优化方法的有效性与可靠性。The marine based pulsed power system(PPS)is composed of a DC/DC converter and a pulsed load,and its power impact characteristics is directly affected by the converter parameters.Considering the different switching frequency characteristics of the converter and the pulsed load,the PPS dynamic process modeling and the optimization method of the converter parameters are proposed.The PPS dynamic process under different switch state combinations is analyzed,an equivalent calculation method for the converter on-off time of the PPS multi-dynamic processes is proposed,and a state equation of PPS with the parame⁃ters of converter inductor and capacitor is established.Taking the optimization of PPS voltage and current characteristics as the objective,the optimization model of inductor and capacitor in DC/DC converter is established and solved by the non-dominated sorting genetic algorithm-Ⅱ(NSGA-Ⅱ).An integrated ship power system with PPS is established respectively in MATLAB/Simulink and RT-LAB,and the results verify the effectiveness and reliability of the proposed modeling and optimization method.
