    摘要:

    并联DC/DC变换器之间的交互影响给系统的稳定运行和电能质量带来负面影响。基于状态空间平均法建立了升压DC/DC变换器传递函数模型,基于所建立的模型和相对增益矩阵原理,提出了一种并联DC/DC变换器双闭环均流控制回路之间的交互影响的分析方法,能够分析并联DC/DC变换器双闭环控制回路之间的交互影响和系统频率、控制参数之间的关系。基于相对增益矩阵原理分析方法和时域仿真的一致性,验证了该分析方法的有效性。

    Abstract:

    Interactive influences among DC/DC converters bring negative effects to stable operation and power quality of the power system. Based on the state space averaging method, the transfer function model of parallel boost DC/DC converter is established, and based on the established model and the relative gain array (RGA) principle proposed DC / DC converter with double closed loop and current sharing control between the interaction analysis method, which can analysis on interactive relationship among double closed loop control circuits of DC / DC converter and the relationship between the control parameters and system frequency. The effectiveness of the proposed method is validated by the consistency of the results of the analysis results of frequency based dynamic relative gain array(DRGA) with the time-domain simulation.
