DC–DC conversion powering for the CMS tracker at SLHC [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2011
Abstract A tracker powering scheme based on DC–DC converters close to the detector modules can supply more power through thinner cables. This will allow to satisfy the increased power demands of tracking systems at the SLHC. This article describes the development of DC–DC converters for upgrades of the CMS pixel and tracking systems and addresses ...

Power Factor Corrector with Bridgeless Flyback Converter for DC Loads Applications

open access: yesEnergies, 2018
Since power systems with a DC distribution method has many advantages, such as conversion efficiency increase of about 5⁻10%, cost reducing by about 15⁻20% and so on, the AC distribution power system will be replaced by a DC distribution one.
