Abstract
The invention relates to an insulated DC-DC converter, in particular for a motor vehicle, comprising—a first circuit, connected to a first electrical grid, and including a primary branch comprising at least one induction coil, —a second circuit, connected to a second electrical grid, and comprising a secondary branch comprising at least one induction coil, each induction coil of the primary branch being coupled with an induction coil of the secondary branch in order to form a transformer. According to the invention, said converter comprises at least one additional branch comprising at least one additional induction coil, said at least one additional branch being connected to the electrical grid, and said at least one additional induction coil being coupled with an induction coil of the secondary branch so that, according to one operating mode, the insulated DC-DC converter transfers energy from the low-voltage vehicle electrical grid to the electrical grid, in particular for pre-charging purposes.
