The ARENA is a scientific underwater cable network having a mesh-like cable topology. It deploys many kinds of sensors in a vast research area in the deep sea, and provides long-term continuous data. In order to made it possible to adopt the constant current power feeding system, which has many advantages including robustness against cable shunt faults, a current-to-current converter was proposed...
Power feeding is the most challenging technical issue to realize mesh-like underwater cable networks of scientific observatories which enable long-term continuous three dimensional and real-time observations. The authors developed a new prototype of the current-to-current converter, which is the key device to realize a constant current power feeding system. The results show that the compact-sized...
