It is known that in the incoming years, the evolution of the LHC experiment (HL LHC) will demand higher efficiency and performances of all the instrumentation used in the hostile environment of the experiment itself.
One of main targets is to position the power conversion system on the particles detectors directily, or in the very nearby, thus reducing the number of conversion stadiums actually existing.
The power supply systems of the paticles detectors will be exposed to enhanced magnetic fields and ionizing radiations.
Compared to the existing systems, the levels of tolerance to magnetic field and radiation of the new ones will have to be increased of a 10-20 factor.
