摘要： 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).

摘要： Verifying system and method for verifying the disconnecting means of a DC/AC converter which are connected in series through a midpoint (5, 6, 7) in each phase (L1, L2, L3) between the converter (3) and a power grid (4). The system comprises voltage detectors (90, 91, 92, 93) and a control unit (8) communicated with said detectors (90, 91, 92, 93) and configured for determining the status of the disconnecting means (1a, 1b, 1c, 2a, 2b, 2c) depending on said voltages. The detectors comprise a detector (91, 92, 93) associated with each phase (L1, L2, L3) for measuring the voltages (V' L1-N , V' L2-N , V' L3-N ) between the corresponding midpoint (5, 6, 7) and the neutral (N) of the power grid (4), and an additional detector (90) for measuring the voltage (V' O-N ) between said neutral (N) and a reference point (O) of the converter (3).
