Measurements on the bPOL48V DC-DC Converter for a Future Particle Collider — Lutz Feld, Katja Klein, Martin Lipinski, Alexander Pauls, and •Joëlle Savelberg — 1. Physikalisches Institut B, RWTH Aachen

The bPOL48V is a DC-DC Point-Of-Load (POL) converter characterized in collaboration with CERN under the DRD7 program, a new Detector R&D initiative to develop future electronic systems and technologies for particle physics detectors. The bPOL48V enables power distribution by converting a 48V input to a 12V (adjustable) output voltage. This enables distribution at higher voltage and reduced current in supply cables, enhancing overall system efficiency by minimizing the power loss.

The bPOL48V consists of a rad-hard controller designed at CERN (GaN Controller), which is capable of continuous operation up to a high radiation limit of 50 Mrad and in magnetic fields exceeding 4 T. The GaN controller operates in conjunction with a power stage featuring a GaN chipset from EPC (EPC2152). This combination provides performance in harsh radiation and magnetic field environments, making it a potential solution for power distribution in high energy physics experiments.

This talk focuses on the tests conducted with the bPOL48V in various setups and the resulting performance. Key aspects include the converter's efficiency, temperature dependency, noise characteristics, and its ability to maintain a stable output voltage despite variations in input voltage and current.
