topIntroduction

End of 2010, CERN launched a R2E program which includes the study of Radiation tolerant power converters design, called R2E Power Converters.

topR2E/EPC Irradiated Units Management

Irradiated units management strategy is organized and defined at the level of the group TE-EPC.

topR2E/EPC Project Management

R2E projects have been organized for a maximum efficiency in dissociating the already hard power design phase from the rad-tolerant consideration. This allows people and teams working in parallel, limiting the impact of each team on each other. A fundamental principle highlighted in this organisation is the natural flexibility of a power converter designer regarding to the component choice, once all choice criteria have been identified in the considered design.
Of course some additional design rules are taken in account at the design level, but not changing drastically the original design methods however aiming for a simple design relying on robust components of few families and types.
