An electrical power converter unit () includes: a first connection interface () comprising two leads () forming a DC input/output interface for connecting a first electrical device to the power converter unit, a three-phase rectifier power converter circuit () and a second connection interface () for connecting a second electrical device to the power converter unit. The second connection interface includes a switching unit () adapted to switch between:&#x2014;a DC input/output mode, in which first, second and third arms of the power converter circuit () are electrically connected together, forming one DC input/output; and&#x2014;an AC input/output mode, in which the arms are disconnected from each other, forming separate input/outputs for a three-phase AC voltage.

A system for charging a battery from various three phase or single phase grid supply voltages includes a full wave bridge rectifier for receiving the AC supply voltage, two DC to DC converters for receiving unregulated DC output voltage from the rectifier, a first switch connected to a first input line of a first one of the two converters and a second switch connected to a first input line of a second one of the two converters, wherein each of the switches is set to a first position when the supply voltage is at a lower one of the varying voltage levels and to a second position when the supply voltage is at a higher one of the varying voltage levels.
