Current-to-current converter for mesh-like scientific underwater cable networks - a compact-sized prototype

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 current-to-current converter having good electrical characteristics is feasible
