Abstract: A power conversion system includes a unipolar bidirectional power converter with DC terminals and a first controller, and a bipolar bidirectional power converter with DC terminals connected in series with the DC terminals of the unipolar bidirectional power converter and a second controller. The first controller is operable to cause only a positive-valued DC voltage across the DC terminals. The second controller is operable to cause a positive-valued or negative-valued DC voltage across the DC terminals of the bipolar bidirectional power converter so that a total voltage of the power conversion system is the sum of the positive-valued or negative-valued DC voltage across the DC terminals of the bipolar bidirectional power converter and the positive-valued DC voltage across the DC terminals of the unipolar bidirectional power converter.

Abstract: A power generation system includes at least one generator that generates a medium voltage direct current that has a positive DC voltage output and a negative DC voltage output. The system also provides a medium voltage DC (MVDC) cable system with a positive pole cable and a negative pole cable, wherein the positive pole cable is connected to the positive DC voltage output and the negative pole cable is connected to the negative DC voltage output. A substation is connected to the MVDC cable system and includes at least one DC/DC step-up converter to step-up the medium voltage direct current to a high voltage direct current.
