Abstract: An electrical three-phase AC-DC converter includes first and second converter stages and a controller. The first converter stage converts between three phase AC terminals and first and second intermediate nodes. The second converter stage has a boost circuit to convert between fourth and fifth intermediate nodes and first and second DC terminals. A link connects the first and second intermediate nodes to the fourth and fifth intermediate nodes. A phase selector selectively connects the three phase terminals to a third intermediate node and a current injection circuit connects the third intermediate node to the first and second DC terminals. In a mode, a current path through the third intermediate node is obtained acting parallel to a current path through the first intermediate node, through the second intermediate node, or through the first and the second intermediate nodes in alternation.
