In this paper, a small-signal model of voltage source converter (VSC) is developed to investigate the stability of dc-link voltage control. This model contributes to representing the dc-link voltage dynamics characteristics of VSC integrated to weak grid. Effects of grid strength, operating point, and control loops' interactions on the performance of VSC are taken into consideration. Based on the proposed small-signal model, eigenvalue analysis is employed to study the stability of dc-link voltage control with varying operating conditions. Analysis results show that control loops' interactions introduce a partial positive feedback to the dc-link voltage control in weak grid. Furthermore, the effect of control loops' interactions on dc-link voltage control stability reaches largest when the bandwidth of the phase-locked loop is close to that of the dc-link voltage control. Time-domain simulations and experiments were conducted to validate the analysis.
