PBF
PBF is a worldwide operating company specialised in
switched mode power supplies and higher level
power solutions.
PBF is a fast growing company which is strongly
driven by technological innovation. This leads to
state of the art design solutions which are beneficial
for our customers. Also for this reason companies
like Philips, Bosch, Thales, FEI Electron Optics and
Coherent made their choice for PBF.

voltages of each converter unless each converter is individual
controlled, which makes the design very complex

Optimization of KM3NeT Optical Module
Conclusion
Contacts work both directions:
-Learn from industrial company expertise for KM3NeT
-What can we expect from industry?
-Innovation, future demands from customers to industry
Usefull input to be taken very seriously
However, we have to make our own decisions
