Abstract	A distinguish feature of LHC detectors is the enormous number of front-end electronics (FE) channels in all of the sub-detectors. Low-voltage power supply systems in the range of multi-kilowatts are required to bias such electronics read-outs. Several configurations has been proposed and analysed by the different groups showing particular advantages and disadvantages. For the CMS detector, the Hadronic Calorimeter (HCAL) and the Muon End-caps (EMU) have proposed a DC power distribution system based on DC-DC power switching converters located in the cavern near the FE. The main advantage of this topology is the reduction in volume of the distribution cables due to the relative low primary currents. Locating the DC-DC converters in the hostile environment of the detector cavern is a disadvantage due to the presence of magnetic field and radiation. In this paper, guidelines for the system design and selection of the components are presented. Additionally, some tests conducted to validate the application of commercial units are reported and future tests are described.
