    摘要： The invention relates to a method for determining the capacitance of an energy store (A1, A2) of a direct current supply unit for the uninterruptible supply of direct current to a load (L), the direct current supply unit comprising at least one input (E) for an input voltage, one output (A) for a DC output voltage, and two identical energy stores (A1, A2) which provide a standby DC output voltage in buffer mode. To determine the actual capacitance without jeopardising a buffer mode, the following steps are provided: in a first step, a charged first energy store (A1) is fully discharged at predefined intervals via a load (L) applied to the output (A); in a second step, the first energy store (A1) is charged from the fully charged second energy store (A2); and in a third step, the second energy store (A2) is fully charged again via the input (E); wherein the capacitance taken from the second energy store (A2) is measured in the second step and/or the capacitance in the charged second energy store (A2) is measured in the third step.

    摘要： The invention relates to a converter for converting an input-side alternating current (U
    N ) into an output-side DC current (U
    sek ), a power factor correction being provided and the converter comprises a transformer having at least two serially arranged primary windings (L
    p 1, L
    p 2). Also, a first switch (S1) is used to switch a storage capacitor unit (C
    Sp ) in series with a first primary winding (L
    p 1) to the alternating current (U
    N ) in a clocked manner via rectification elements (GD1, GD2, GD3, GD4) and a second primary winding (L
    p 2) can be switched to the storage capacitor unit (C
    Sp ) in a clocked manner by means of a second switch (S2).

    摘要： The invention relates to a flux converter for converting an input-side alternating current (U
    N ) into an
    output-side DC current (U
    sek ), a power factor
    correction being provided and the flux converter comprises a transformer having at least two serially arranged primary windings (Lp
    1 , LP
    2 ) and a secondary winding (L
    sek ) wound in same direction. Also, a first switch (S1) is used to switch a storage capacitor (C
    Sp ) in series with a first
    primary winding (L
    p 1) to the alternating current (U
    N ) in a clocked manner via rectification elements and a
    second primary winding (L

    摘要： 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).
