| Abstract | Efforts aiming at consolidating the powering for the CMS detector have led to the development of a Low Voltage Power Supply (LVPS). The LVPS converts 380 V DC to 12 V DC, suitable for powering the widely used bPOL12V point-of-load DC-DC converter. To limit cable size, the LVPS must be hosted in the CMS experimental cavern, being exposed to ionizing radiation and stray magnetic field of up to 120 mT. The device is made of Commercial Off-The-Shelf (COTS) components, therefore, thorough qualifications at various design stages were performed to ensure its reliable operation in the harsh environmental conditions for the HL-LHC era. |
