Abstract: A power converter. The power converter comprising: two or more multi-phase AC sources; an AC-DC converter circuit for each of the multi-phase AC sources, each AC-DC converter circuit being connected to a respective multi-phase AC source via a multi-phase input and configured to rectify a received multi-phase current into a DC current; a transformer, which is connected between the multi-phase AC inputs; a DC-link, shared between each of the AC-DC converter circuits; a load, connected to the DC-link and able to receive DC current therefrom; and a common mode filter, located within the DC-link, and configured to reduce a circulatory current which, when the power converter is in use, flows from the transformer through one of the AC-DC converter circuits, through the DC-link and through a further of theAC-DC converter circuits back to the transformer.
