The invention relates to a power supply system having two power storage devices (1), which according to the invention, is suitable for being used in a motor vehicle or in a hybrid vehicle. The power supply system is to be connected to a power network (5) of the vehicle. The power supply system includes a first power storage device (2) having a first specific energy and a first specific power, and a second power storage device (3) having a second specific energy that is lower than the first specific energy, and a second specific power that is greater than the first specific power. The first and second power storage devices are electrically connected by a bidirectional DC-DC converter (4) controlled on the basis of the states of operation of the vehicle. According to the invention, the DC-DC converter is, at least in part, floating with respect to a reference line (13) of the power network (5).
