Abstract :
The LHC (Large Hadron Collider) particle accelerator makes extensive use of true bipolar power converters, with a high precision regulated output current requirement. A special design and topology is required to allow high performance within the converter operating area, including quadrant transition. This paper presents the +120 A +10 V power converter, well represented in the LHC power converters (300 units). The design is adapted for a wide range of magnet loads [from 10 mH to 4 Henry] (time constant load [0.1 s.. 1050 s]) with stringent EMC requirements. A quick-connect system was applied to the converter modules allowing easy installation and maintenance operations. Discussion of 4 quadrant control and practical results are presented.
