These include reduced energy storage, reduced turn-on time and enhanced energy density when compared with
existing topologies. Preliminary practical results are promising and are presented along with simulation results.
Diamond Booster Magnet Power Converters
This paper will describe the design, factory
tests, commissioning and early operation of
the Diamond Booster Power Converters. The
Power Converters covered are the Dipole,
Quadrupole with two outputs, two bi-polar

Sextupoles and 44 Steerers. The actual achieved performance will be compared with the specification and the extensive
modelling that was carried out during the design phase. The design includes measures to enhance the reliability
of the power converters, such as redundancy, plug-in modularity, component de-rating and component standardisation.
All the Diamond power converters use the same digital controller, manufactured under licence from the Paul
Scherrer Institute.
Diamond Storage Ring Magnet Power Converters
The DC Magnet Power Converter requirements
for the Storage Ring of the Diamond
Project are described together with performance,
commissioning and initial operating
experience. In addition to meeting the re-

quired performance, emphasis during the design phase was placed on reliability and minimising the mean time to
repair a power converter. A modular design, built-in redundancy, EMC filtering and testing, component de-rating and
standardisation have all been adopted. The power modules for the 200A supplies were subject to highly accelerated
stress screening. All converters are switched mode with full digital control and a common control interface. Every
power converter appears identical to the Controls Network, from the lowest power corrector up to the 800 kW Storage
Ring Dipole Converter.
CNAO Resonance Sextupole Magnet Power Converters
The CNAO Resonance Sextupole Magnet
Power Converter requirements for the Storage
Ring of the CNAO Project are described
together with performance and initial operating
experience. In particular the achieved
performances will be compared with the

specification and the extensive modelling that was done during the design phase. Not only the tight required
performances were emphasized during the design phase but also particular attention was put on reliability and minimization
of the repairing time (MTTR). Some fundamental criteria, like component de-rating and standardisation,
have also been taken into account during the component choice phase. All converters adopt the switching technology
with full digital control and a common control interface, that, as for the other CNAO power converters, uses the same
digital controller, under licence from the Diamond Light Source.
