Definitions

• Power Converter or Power Supply
  Electrical Power System which includes at least: a Power Source, a Controller and a Sensor.


• Power Source
  Electrical system which adapts energy source quantities (e.g. voltage, current) to a load following a given reference.
  A Power Converter often uses a Voltage Power source, commonly called Voltage Source.


• Load
  System connected to the Power Source's output terminals, usually a magnet (R-L Series eq. circuit).


• Power Part
  Mechanical and electrical parts of the Power Source which deal with high voltage/current levels (> 50 V or > 1 A).


• Output circuit
  The circuit in the Power Source that links the isolating device (transformer) and the output terminals.


• Control Part
  Power Source’s low-voltage (< 50 V, < 1 A) logic/analog signals related to systems controlling the Power Part.


• Controller
  A device placed interacting with the CERN Control Centre (CCC) and the Power Source, which
  • Acts as a standardization layer for the CCC
  • Manages Power Source diagnostics and control, and generates the Power Source reference.


• Sensor
  Device which measures a quantity (e.g. a hall-effect current probe, a DCCT in case of a current sensor).


• Interlock Controller
  System managing the interlock system, interacting with the Power Converter and ensuring people and Load safety.
