Abstract
The invention relates to a voltage converter (100), including: a plurality of two-way conversion cells (303), each cell comprising a primary circuit (307, Wp), and a secondary circuit (308, Ws) that is insulated from the primary circuit, wherein each circuit can be separately activated in order to supply an output voltage from the converter; and at least one control circuit (306) configured to, in a first operating mode, control the activated cells in order to transfer electrical energy from the primary circuit to the secondary circuit, and control the inactivated cells in order to transfer electrical energy from the secondary circuit to the primary circuit.
