The invention relates to a power supply apparatus and also to a power supply arrangement. The power supply apparatus comprises an interface to the load. The power supply apparatus also comprises at least one controllable solid-state switch, for supplying power between the aforementioned load and the power supply apparatus. The power supply apparatus comprises a controller, which is fitted to control the at least one controllable solid-state switch at the selected switching frequency. The switching frequency is selected such that the noise of the load corresponding to the selected switching frequency meets the selection criterion.
