The invention relates to a power supply with a DC-DC converter (2) and a switching converter (1), an intermediate circuit (3) with an intermediate circuit voltage is provided, wherein the intermediate circuit (3) can be connected to a supply voltage via the DC-DC converter (2) and at least one output switching regulator (11, 12, 3, 1n, 14, 15, 16, 1m) is connected to the intermediate circuit (3), said switching regulator supplying, on the output side, a regulated output voltage (Out1, Out2, Out3, Outn, Out4, Out5, Out6, Outm). The intermediate circuit voltage is not controlled. Instead, the intermediate circuit voltage is obtained from the energy supplied by means of the DC-DC converter (2) and the energy extracted by means of the output switching regulator (11, 12, 13, 1n, 14, 15, 16, 1m). |
