Abstract
This paper focuses on the arm-reuse high-voltage DC transformer, establishes its impedance model, and proposes a quantitative stability analysis method based on the Nyquist criterion. Through frequency-domain sensitivity analysis, the critical influence of dominant parameters in the mid- frequency and high-frequency bands on stability is identified, along with the regulating effect of low-frequency parameters. Time-domain simulations verify the validity of the theoretical analysis, and a segmented parameter-tuning strategy is accordingly proposed, providing a basis for optimizing system stability.
