Due to the increase in granularity and higher complexity of the front end electronics needed at the SLHC, an upgrade of the CMS silicon strip tracker is expected to require even more power than the current CMS strip tracker. However, the space available for cables will remain the same as today. In addition, a further increase of the material budget due to cables and cooling is not acceptable...

Buck topology is the workhorse in most of the power electronic devices. Buck converter is step-down DC to DC converter. It utilizes two switches (two FETS or one FET and one diode) along with an output inductor and output capacitor.
Whether you look at the large computer server, personal computer Desktop or laptop, cell phone or GPS unit all will contain a buck topology design in one form...

The costs, difficulties and inefficiencies associated with the cabling of silicon detector systems are well known. Serial Powering is an elegant solution to these issues and is being actively pursued by the ATLAS Tracker upgrade community.
Demonstrator supermodules have been produced using the ABCD chip from the present ATLAS SCT together with serial powering circuitry built from commercial...

For future hep experiments, especially for LHC upgrades new powering schemes are required. The SPI001 (Serial Powering Interface) chip has been designed and fabricated to explore the serial powering approach.
Main features of the chip are a programmable shunt regulator (handling at least 1A) and two linear regulators providing module voltages, current mode ADCs monitoring shunt and linear...

The Detector Control System (DCS) of the power supply of the Monitored Drift Tubes (MDT) detector of the ATLAS experiment at CERN will be presented. The principal task of DCS is to enable and ensure the coherent and safe operation of the detector. The interaction of detector experts, users or even shifters with the detector hardware is performed via DCS. This is the responsible system of...

The conducted and radiated noise that is emitted by a power supply constrains the noise performance of the front-end electronics system that it powers. The characterization of the noise susceptibility of the front-end electronics allows setting proper requirements for the back-end power supply in order to achieve the expected system performance. A method to measure the common mode current...
