    摘 要:研究了双向 DC/DC 拓扑的蓄电池守护装置的谐波稳定性问题。针对常见的双向 DC/DC 拓扑建立了系统的时域稳态模型,通过傅里叶变换映射至基于谐波状态空间的频域谐波模型,分析了系统中的电力电子非线性元件及调制方式对直流输出电压的影响。通过构建谐波传递函数,采用广义奈奎斯特稳定判据分析了不同控制参数下谐波模型的稳定性。基于 MATLAB/Simulink 仿真平台,验证了所建模型的正确性及分析方法的有效性。

    Abstract: The harmonic stability of battery guardian devices in bidirectional DC/DC topology was studied in this paper. Firstly, the time-domain steady-state model of the system is established for the common bidirectional DC/DC topology, and then the influence of the nonlinear components and modulation modes of power electronics on the DC output voltage is analyzed by mapping to the frequency domain harmonic model based on harmonic state space by Fourier transform. By constructing the harmonic transfer function, the stability of harmonic models under different control parameters is analyzed by using the generalized Nyquist stability criterion. Finally, based on the MATLAB/Simulink simulation platform, the correctness of the model and the effectiveness of the analysis method are verified.
    Key words: bidirectional DC/DC topology; battery guard device; harmonic state space; harmonic transfer function; generalized Nyquist
