A Flexible AC/DC-Link is supposed to work robustly in both AC and DC operation modes. In relation to the DC-mode, the most important aspect of the system is to present enough robustness to maintain a reliable power supply. Thus, DC-link experimental tests focus on the system's stability at various transient events, such as the connection of generators, load changing, among others. The aim of this study was to investigate the system's stability response when facing a sudden load increase or decrease. An experimental lab setup was created in order to analyze the stability and robustness of a Flexible AC/DC-Link. Likewise, this paper also addresses the main system's outcomes to be taken into account when a system is submitted to large amounts of load variation.
