摘要：
In this paper, the inductor current feedback based droop control was proposed for bi-directional DC-DC converter widely used in DC microgrid. The operation principle of the traditional droop control with the output current feedback for bi-directional DC-DC converter was analyzed. And then the stability of the double closed-loop control for the bi-directional DC-DC converters with the outer loop voltage control and the inner inductance current control was analyzed in detail. Furthermore, the proposed droop control method based on inductance current feedback was proposed and the stability of the proposed method was elaborated. The proposed can effectively improve the control system stability of the DC-DC converter with the power sharing ability. The experimental tested verify correctness and effectiveness of the control system. © 2020 Chin. Soc. for Elec. Eng.
