Abstract

The large hadron collider (LHC) is the next particle accelerator being constructed on the CERN site. The 27 km long accelerator requires many high current (multi-kA) power converters to supply the superconducting magnets. This paper describes the development of a modular high current power converter, capable of supplying up to [8 kA, 8 V] using several current sources of [2 kA, 8 V] in parallel. Production aspects and test results of 200 power converters are presented and analysed
