| 摘要 |
The invention relates to a system for balancing an association in series of elements for generating and/or storing electrical energy, characterised in that it comprises: a plurality of full bridge inverters (OPC1, OPC2, OPCN), each consisting of two inverter arms connected in parallel between two end ports of the inverter, each inverter arm, in turn, consisting of two switches (Th1, Tb1; Th2, Tb2) connected in series by a so-called median point (P11, P12) of the arm; a plurality of connectors for connecting the two end ports of each full bridge inverter to a respective element (CA1, CA2, CAN, PV1, PV2, PVN) of said association in series; and a magnetic coupler (NM) formed by a magnetic core on which a plurality of windings (ŴW2, WN) is formed, each winding being connected to the median points of the arms of one of said inverters. The invention also relates to an association in series of elements (CA1, CA2, CAN) for the electrochemical storage of electrical energy, provided with such a balancing system. The invention further relates to an association in series of photovoltaic cells (PV1, PV2, PVN) provided with such a balancing system. |
