DUAL VOLTAGE ELECTRICAL DISTRIBUTION SYSTEM

For vehicles with two electrical networks and corresponding charges at two different voltage levels, with two batteries at a first and at a second voltage level respectively, to which two networks a bi-directional converter is associated, with its input and output stages galvanically insulated, each of which includes a switching device to whose input and output the said batteries are connected at a first and at a second voltage level, so that said bi-directional converter provides a first mode of voltage reduction and a second mode of voltage raising, having chosen the passive components, that is, the magnetic components and capacitances of said stages to provide an identical transitory behaviour in both modes when a disturbance enters the regulation system whether in the charge or in the input voltage.
