Abstract
According to an embodiment, a power generation system is provided comprising a power generator; a plurality of converter modules, each converter module having a DC link, wherein the DC link of each converter module is connected to the DC links of the other converter modules of the plurality of converter modules via a fuse associated with the converter module; and a controller configured to, if it is detected that there is a fault in one of the converter modules, disconnect the converter module in which there is a fault from the power generator and connect two or more other converters module of the plurality of converter modules to the power generator and to control the power generation system to supply power to the DC links of the two or more other converter modules such that power is supplied to the converter module in which there is a fault via the fuse associated with the converter module such that the fuse associated with the converter module melts.
