| Abstract |
This paper presents an active stabilization method of the dc-link voltage in voltage-source converters. It is a direct compensation method, acting on the converter command voltages instead of the current loop reference, which allows for a wider bandwidth. The proposed method is compared to the state-of-the-art direct compensation method, i.e. filtering the dc-voltage used in the pulse-width-modulation process. The effectiveness of the proposed method over the complete operating range is demonstrated with theoretical analysis and simulation results. |
