Design Concepts for Medium Voltage DC Networks supplying the Future Circular Collider (FCC) / Colmenero, Manuel (CERN) ; Blanquez, Francisco R (CERN) ; Blasco-Gimenez, Ramon (Valencia U., IFIC)
In the frame of the feasibility studies for the construction of the Future Circular Collider (FCC), a new particle accelerator of 90 km of circumference under design, the use of Medium Voltage DC Grids (MVDC) for distribution has attracted attention considering their potential advantages in terms of transmission losses, power flow control and energy storage integration. Traditionally, the main concerns of the DC networks have been their reliability and robustness. [...]

Control strategy for an interleaved converter based on parallel H-bridge structures / Garcia Retegui, R (U. Buenos Aires) ; Wassinger, N (U. Buenos Aires) ; Maestri, S (U. Buenos Aires) ; Pittet, S (CERN) ; Burnet, JP (CERN)
In order to supply the new inner triplet magnets of the High Luminosity Large Hadron Collider (HL-LHC) with the required 18kA of DC current, new power converters are under development. Given the demanding requirements on current, efficiency, dynamic response, precision and availability, the use of a modular converter structure based on parallel operation of N sub-converters with M parallel H-bridges inside is adopted, as this strategy allows to continue operation even under a fault scenario. [...]

A Reliability and Efficiency Optimization System for Hard-Switching DC/DC Converters / Ripamonti, Giacomo (CERN) ; Michelis, Stefano (CERN) ; Faccio, Federico (CERN) ; Saggini, Stefano (Udine U.) ; Koukab, Adil (Ecole Polytechnique, Lausanne) ; Kayal, Maher (Ecole Polytechnique, Lausanne)
The Large Hadron Collider experiments at CERN will use power distribution schemes relying on integrated buck DCIDC converters. Due to the radiation-hardness requirements, the devices used for the development of such converters will have a voltage rating which is close to the converters' input voltage. [...]

An Integrated Regulated Resonant Switched-Capacitor DC-DC Converter For PoL Applications / Ripamonti, Giacomo (CERN) ; Michelis, Stefano (CERN) ; Ursino, Mario (U. Udine (main)) ; Saggini, Stefano (U. Udine (main)) ; Faccio, Federico (CERN)
This paper proposes an integrated regulated resonant switched-capacitor DC-DC converter for a 2.5 V to 1.2 V, 3 A conversion designed in a 130 nm CMOS technology. The voltage is regulated through a combined frequency/time shift on-chip controller that operates thanks to a zero-crossing detector for the tank current. [...]
