Description
The Phase-II upgrade of the ATLAS Tile Calorimeter requires a reliable Low Voltage Power Supply (LVPS) system capable of stable operation under High-Luminosity Large Hadron Collider (HL-LHC) conditions. As part of the production quality assurance chain, a single-brick test bench has been upgraded to perform initial functional validation of LVPS converter boards prior to burn-in and system-level integration. Each LVPS brick is designed to deliver approximately ~10 V output at load currents in the range of a nominal ~2.3 A, corresponding to output powers of up to ~70 W, with expected efficiencies above 60 %. The test bench enables controlled electrical characterisation of individual bricks, including measurements of output voltage regulation, load current stability, input current behaviour from the ~200 V DC supply, and conversion efficiency. This initial test stage serves as a critical filter in the production pipeline, enabling early identification of faulty or non-compliant units before burn-in testing. The results demonstrate that the test bench provides reproducible and quantitative validation of brick performance, ensuring consistency across production batches and contributing to the overall reliability of the LVPS system.
