Abstract
An electrical power converter unit (2) includes: a first connection interface (10) comprising two leads (12, 14) forming a DC input/output interface for connecting a first electrical device to the power converter unit, a three-phase rectifier power converter circuit (16) and a second connection interface (30) for connecting a second electrical device to the power converter unit. The second connection interface includes a switching unit (46) adapted to switch between:—a DC input/output mode, in which first, second and third arms of the power converter circuit (16) are electrically connected together, forming one DC input/output; and—an AC input/output mode, in which the arms are disconnected from each other, forming separate input/outputs for a three-phase AC voltage.
