    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
