摘要
A switched-mode power supply unit for a computer includes at least one switching element that switches a charging current to charge a storage element, at least one secondary output circuit that provides an output voltage (Vout+), at least one controllable oscillator circuit that provides a switching clock, and at least one control circuit that determines a switch-off time for the at least one switching element, wherein, in operation of the switched-mode power supply unit, a mean oscillator clock of the oscillator circuit is controlled in dependence on a controlled variable (Vcontrol) specifying the output voltage or power of the secondary output circuit such that the mean oscillator clock rises monotonously with the output power and a switch-on time for the at least one switching element is determined in dependence on the mean oscillator clock and a random deviation.
