A high current switch mode power converter, designed for powering of superconducting loads requiring only positive current and positive voltage control (1 quadrant). Constructed from a modular architecture composed of 2kA power modules, the system can be easily adapted to suit specific powering requirements. Used extensively in the LHC particle accelerator. The converter is water cooled, and is thus ideally suited to situations where air losses must be carefully managed. Designed for underground operation, extensive remote diagnostics have been foreseen to allow efficient monitoring and fault diagnostics without requiring being present locally.

Simplified Schematic

Notes:

This topology gives a very low output EMC noise. The free wheeling diodes are assuring the current path, independent of the converter status, during the natural current decay.
