Five years of operational experience with digitally controlled power supplies for beam control at the Paul Scherrer Institut (PSI)

Precise beam control is a crucial requirement for the operation of particle accelerators. High-precision power supplies for beam guiding are essential. For the Swiss Light Source a new digital power supply control technology was developed and implemented. A large number of power supplies are equipped with this compact and flexible control system at PSI. Practical experiences of five years of operation are presented
