This report summarises the activities of the CERN/EP strategic R&D programme on technologies for future experiments during the year 2025.

A Monolithic Regulated 160 MHz Resonant DC-DC Converter

Giacomo Ripamonti, Stefano Michelis, Georgios Bantemits, Pablo Antoszczuk et autres

This paper presents a monolithic dual phase 2:1 DC-DC converter featuring a 2.0-2.5 V input range, employing quasi-resonant regulation and using LC resonant tanks with coupled inductors. The output voltage can be regulated in the 0.8 - 1 V range by regulating …

Next generation fully integrated DCDC converters for HEP applications in 28 nm technology

Georgios Bantemits, Giacomo Ripamonti, Khalil Khalife, Mattia Balutto et autres

Abstract For the first time in the High-Energy Physics (HEP) community, a family of fully integrated radiation-hardened DC/DC converters, including all capacitors and inductors, has been developed. This paper presents the experimental results of three functional ASIC prototypes implemented in a 28 …

Hybrid Resonant Switched Tank Converters for High Step-Down Voltage Conversion

Alessandro Dago, Mattia Balutto, Stefano Saggini, Mauro Leoncini et autres

In this article, we propose a new family of modular hybrid resonant switched tank converters (HRSTC) to perform high fixed-ratio 48 V-to-intermediate bus voltage down-conversion in data center applications. These topologies exploit a modular approach to address the challenge of achieving compact …

A 260-A/48-V Bus Hybrid Resonant Converter with Large Conversion Ratio for Future Data Centers

Alessandro Dago, Mattia Balutto, Stefano Saggini, Mauro Leoncini et autres

This paper introduces a novel scalable hybrid resonant converter based on the Dickson switched capacitor converter (SCC) structure for 48 V bus down-conversion. The conversion of the 48 V bus to the CPU/GPU core voltage typically includes a two-step process. First, an …

Switched Tank Converter: Quasi-Resonant Regulation for Soft Start and Mismatch Mitigation Technique

Mattia Balutto, Giacomo Ripamonti, Pablo Antoszczuk, Stefano Michelis et autres

In recent years, there has been a significant increase in the power consumption of data centers. As a result, server rack architecture has shifted from using 12 V to higher voltage levels of 48–60 V. The conventional power delivery system in use …

Quasi-regulation and mismatch mitigation technique for switched tank converters

Mattia Balutto, Giacomo Ripamonti, Pablo Antoszczuk, Stefano Michelis et autres

Data center power consumption has been increasing remarkably in the last decades, mainly due to the massive adoption of cloud computing. Due to the vast amount of power consumed, server rack architecture has switched from 12 V to (48 V – 60 …
