    摘要: A converter system for converting a three-phase or a single-phase AC voltage into a DC voltage, wherein the converter system includes three converter branches, each converter branch including a first input and a second input to be supplied with a single-phase AC voltage and a first output and a second output providing a DC voltage; wherein each converter branch includes an AC-to-DC stage and a DC-to-DC stage, which are connected between the first and second input and the first and second output; wherein the converter system is configured for interconnecting the first input of each converter branch with a phase of a three-phase grid and for interconnecting the first inputs of the converter branches with a phase of a single-phase grid; wherein the converter system is configured for interconnecting the second inputs, which are interconnected with each other, of the converter branches with a neutral point of the three-phase grid or the single-phase grid; and wherein the converter system includes one or more controllers adapted for controlling the converter branches independently from each other.

    摘要: Heat exchanger structure for a rack assembly formed by a shaped body of thermally conductive material. The heat exchanger structure comprises a first heat exchanging portion adapted to provide a mechanical support for one or more power electronic components of said rack assembly and adapted to absorb and dissipate heat generated by said power electronic components. The heat exchanger structure comprises a second heat exchanging portion adapted to provide a mechanical support for one or more power electromagnetic components of said rack assembly and adapted to absorb and dissipate heat generated by said power electromagnetic components.
