Abstract

A power supply unit (1) that is to be connected to different types of power supply networks includes an input (2) to receive AC power from the power supply network and an output (3) for providing power to an electrical device. The electrical device may for example be a computer, a telecom infrastructure device, inductive cooking/heating systems or an on-board charger of an electrical automotive vehicle. The power supply unit (1) includes at least two converters (4) that are connected between the inputs (2) and the output (3) and it further includes a controllable switching arrangement (5). The switching arrangement (5) includes a number of controllable switches (6) to controllably connect the converters (4) in different configurations to the input (2) and therefore also controllably to different supply lines of the power supply network.
