The invention relates to a power conversion system and an associated control method. The system comprises a plurality of converters (3) connected in parallel on an AC side, each converter (3) comprising an AC side (3A) for being coupled to a power grid (G), a DC side (3C) for coupling to a direct-current source (200), and a first terminal (1) and a second terminal (2) on said DC side (3C). The outputs on the AC side (3A) of all the converters (3A) are connected to a common output point, the first terminals (1) of the various converters (3) of the system (100) being earthed, and the second terminals (2) of said converters (3) being independent from one another. Thus, each source (200) is adapted and configured to operate independently of the rest of the sources (200).
