    Abstract: DC Power distribution system The invention relates to a DC power distribution system (1), especially a track lighting system, comprising several power supply units(3) and an electrical consumer (4) like a luminaire electrically connected to an electrical conductor (2)being preferentially a power bar. Apower consumption information providing system providespower consumption information anda power supply control system controlsthe power supply units depending on the provided power consumption information. This allows adapting the DC power distribution tothe actually required power, i.e. several power supply units can be electrically connected to the electrical conductor, without providing DC power in an inefficient operation condition. Moreover, the installation of the DC power distribution system can be relatively simple, because the installer just needs to attach a number of power supply units to the electrical conductor, which surely prevents an overload condition, wherein the DC power can still be supplied with high efficiency.

    Abstract: A power supply control system delivers regulated power to a load via a delivery cable. The power supply control system includes a power stage operable to deliver power to the load at a first regulated voltage level and a second regulated voltage level. A cable offset voltage unit generates an offset voltage signal representing a drop in voltage across the delivery cable. The offset voltage signal is generated based on a first cable drop compensation value when the power stage is operated to deliver power at the first regulated voltage level and based on a second cable drop compensation value when the power stage is operated to deliver power at the second regulated voltage level. A controller coupled to the power stage and the cable offset voltage unit controls the power stage to deliver the regulated power to the load based at least in part on the offset voltage signal.
