The invention relates to a device forming a DC voltage bus for a polyphase electrical system (M), comprising voltage legs (A, A, A) each having a plurality of battery cell modules (C, C, C), each module comprising a battery cell or a cluster of battery cells (c), connected to a DC-to-AC converter (DCAC); said battery cell modules (C, C, C) being connected together in series via the DC-to-AC converter (DCAC); said voltage legs (A, A, A) each being connected to a specific phase leg (B, B, B) for said polyphase electrical system (M), at least one phase leg (B, B, B) having a branch (D, D, D) connected to a rectifier module (R). The invention also relates to a motor vehicle, a renewable energy generator and a method based on such a system.
