Abstract: A direct current (DC) distribution system includes a plurality of power consumer clusters, each comprising at least one power consumer. The power consumer clusters are arranged as a ring structure with a common low voltage (LV)-DC ring bus. Each power consumer is connected to the LV-DC ring bus. The DC distribution system further comprises a plurality of normal-open ring switches. Each power consumer cluster is separated from its adjacent power consumer clusters by one of the normal-open ring switches. Each power consumer cluster is fed by a MV-DC/DC converter, which in turn is fed by a MV-AC/DC converter connected to a MV-AC grid.

Abstract: A multi-pulse line-interphase transformer converter includes an electric part that includes magnetic components configured to be connected to a three-phase AC grid, and an electric part that includes a multi-phase voltage system configured to be connected to a common DC capacitor. The electric part splits each AC grid phase n times into two phases, resulting in a plurality of intermediate phases at an internal interface, each intermediate phase corresponding to a pulse of the multi-pulse line-interphase transformer converter. The intermediate phases are connected to the multi-phase voltage system. The multi-phase voltage system comprises bridges with actively controlled switches. The bridges are connected in parallel to the common DC capacitor.

Abstract: A converter for transferring power from a medium-voltage, MV, to a low-voltage, LV, side is provided. The converter includes at least one DC/AC cell with a MV AC terminal configured for generating an AC voltage from a MV DC voltage, and includes at least one AC/DC cell with a LV AC terminal configured for generating a DC voltage from a LV AC voltage. The converter has a magnetic core with a LV winding, and a LV terminal connected to the LV AC terminal, additionally with a magnetic core with a MV winding, and a MV terminal connected to the MV AC terminal. The converter includes an auxiliary unit with an auxiliary winding, and an auxiliary terminal connected to control circuits for operating the MV DC/AC cell. Galvanic insulation between the LV and the MV winding and the auxiliary winding is configured to withstand the Basic Insulation Level of the converter.
