Abstract (en)
[origin: WO2022214745A1] The invention relates to a device forming a DC voltage bus for a polyphase electrical system (M), comprising voltage legs (A1, A2, A3) each having a plurality of battery cell modules (C1, C2, C3), each module comprising a battery cell or a cluster of battery cells (c1), connected to a DC-to-AC converter (DCAC); said battery cell modules (C1, C2, C3) being connected together in series via the DC-to-AC converter (DCAC); said voltage legs (A1, A2, A3) each being connected to a specific phase leg (B1, B2, B3) for said polyphase electrical system (M), at least one phase leg (B1, B2, B3) having a branch (D1, D2, D3) connected to a rectifier module (R1). The invention also relates to a motor vehicle, a renewable energy generator and a method based on such a system.
