    • The invention relates to an input circuit (1) for an electrical device (2), comprising a common electrical path (18) having a first line filter (4), a first electrical path (6) that is connected in series to the common electrical path (18) and has a second line filter (8), and a second electrical path (7) that is connected in series to the common electrical path (18) and connected in parallel to the first electrical path (6). The input circuit comprises a first switching element (5) for opening the first electrical path (6). In a first operating mode (Z1) having a high power consumption of the electrical device (1), the first switching element (5) is closed, so that a filtration of an operating current is effected by way of the first line filter (4) and the second line filter (8), and in a second operating mode (Z2) having a reduced power consumption of the electrical device (2), the first switching element (5) is opened, so that a filtration is effected only by the first line filter (4). The invention further relates to the use of such an input circuit (1) in a switching power supply unit and to an electrical device (2) comprising such an input circuit (1).

    • The invention relates to a switched-mode power supply unit (100) for a computer or the like. The switched-mode power supply unit comprises at least one switching element (120) for switching a charging current for charging a storage element (130), at least one secondary output circuit, at least one controllable oscillator circuit (160) for providing a switching clock and at least one control circuit (150) for determining a switch-off time for the at least one switching element (120). In this arrangement, operation of the switched-mode power supply unit (100) involves a mean oscillator clock from the oscillator circuit (160) being regulated on the basis of a controlled variable (Vcontrol) from the secondary output circuit (140) and a switch-on time for the at least one switching element (120) being determined on the basis of the mean oscillator clock and a random deviation. The invention likewise relates to a method of operation for such a switched-mode power supply unit (100) and to the use of such a switched-mode power supply unit (100) in a computer.
