A DC-link module composed of a reduced value of DC-link capacitor and a series voltage compensator has been proposed. The voltage compensator processes the ripple voltage on the DC link and reactive power only, which can be implemented by low-voltage devices. The overall energy storage of the DC-link module is reduced, permitting the replacement of electrolytic capacitors by film capacitors in a cost-effective way. This paper focuses on the stability analysis and dynamic performance evaluation of the proposed DC-link module. Theoretical study and experimental verification are presented and the results are compared with the conventional DC-link design solution.
