1700 different power converters or power supplies feed the magnets in the accelerator. (They are known as converters because they convert A.C. to the D.C. required by the magnets. )
What is a power converter at CERN?
The current delivered depends strongly on the magnet type. Some correctors take up to 60 Amps; the main bending magnet circuits take around 11,000 Amps at top energy. The total current delivered is 1.7 million Amps.
The challenge of CERN: Precision, repeatability, stability and reliability
