Abstract:
The fourth-generation corrector electromagnets of the SOLEIL synchrotron require compact switch mode power supplies (SMPS) with high dynamics in the transition phases, low residual output ripple of few ppm, good EMC performance and good efficiency. To achieve this, the study of a low-power bipolar DC-DC converter with a high switching frequency is in progress. A technological comparison between GaN HEMT and Si MOSFET based SMPS is proposed on the different criteria of the specifications.
