    Abstract: A high voltage power supply comprises a three-phase high voltage transformer (3) and a three-phase high voltage bridge rectifier (4). A primary side of the transformer (3) has three input terminals connectable to the phases (A, B, C) of an industrial three-phase mains net, and a secondary side of the transformer (3) has three output terminals connected to three corresponding input terminals of the bridge rectifier (4). The bridge rectifier (4) is configured to supply a rectified high voltage to a load (2). The power supply further comprises a switching device (22) configured to switch between a first state, in which all input terminals of the transformer (3) are connected to corresponding phases of the net for operation in a three-phase mode, and a second state, in which at least one of the input terminals of the transformer (3) is disconnected from the net for operation in a single-phase mode.
