A power conversion system including a triple active bridge (TAB) is provided. The system includes a power factor correction (PFC) module and a three port converter (TPC) module, with no post-regulation or additional stages required. The TPC module includes an OBC full-bridge and an APM full-bridge, each being inductively coupled to the output of the PFC full-bridge, thereby forming the TAB. The OBC full-bridge is adapted to convert an AC input into a high-voltage DC output for a high-voltage battery, and the APM full-bridge is adapted to convert an AC input into a low-voltage DC output for a low-voltage battery. The power conversion system can accept a single-phase AC input and a three-phase AC input, has a lower current stress as compared to prior art TPCs, and freely transfers power from among any ports.

The present invention aims at developing a robot for applying coating in regions called “difficult access areas” of offshore platforms and ships, such as curved, vertical surfaces, or surfaces with negative inclination angles. The design concept was developed based on a low-weight painting system, integrated into a vehicle with magnetic shoes (104), which produces a constant magnetic force on the metallic surface, capable of guaranteeing the support of the vehicle in the different areas of application. The floating magnetic system aims at ensuring that the wheels (102) have the necessary friction for the vehicle to move. The use of the equipment allows greater productivity, with agility and speed in the application of coatings, reduction of coating losses during the process, repeatability and guarantee of the thickness of the applied layer, in addition to allowing the application of the coating on vertical surfaces, with negative inclinations or curves, without the need for access using scaffolding, dispensing with scaffolding assembly and disassembly services and the use of ropes by professionals for work on the sea, with the consequent reduction in the number of workers on the sea and the reduction of exposure of the man in unhealthy environments.
