The system proposed in this invention allows the conversion of energy from an AC/DC source, located on a platform (surface) and transmitted through an umbilical to a robot that operates on flexible lines, converting the electrical voltage to levels suitable for supplying the robotic system, and can also be used for supplying other pieces of equipment that operate with low voltage and require power high-density and protection against voltage transients. The system of the invention consists of a surface source (), fed by the platform's three-phase grid (), an umbilical cable (), which connects the source to the robot, an overvoltage protection circuit (), and a two-stage conversion modular system (and).
