Power Converter

Abstract

To provide a power converter having a magnetic link that can lower the overall volume and cost while having strong coupling in the magnetic link. A power converter comprising: an AC to DC bidirectional power converter cell with two stage-power conversion from AC to DC and DC to DC in each of three-phase, wherein one power electronic converter of the AC to DC bidirectional power converter cell converts AC to DC, and two power electronic converters isolated by a two-winding high frequency isolation transformer of the AC to DC bidirectional power converter cell converts DC to DC, wherein a coupled inductor is connected in a DC-DC conversion stage of the two-stage power conversion such that the coupled inductor is in series and in between a first power electronic converter and the two-winding high frequency isolation transformer of the AC to DC bidirectional power converter cell, wherein the coupled inductor connects each of three-phase magnetically.
