A recently granted patent (Publication Number: US11958578B2) discloses a power supply system designed for marine applications. The system comprises at least two segregated power sections, each including a main redundancy group with a main switch board, a power generator, and a power consumer. Additionally, directly powered thruster redundancy groups are connected to the main switch boards to receive AC power through AC interconnections. An indirectly powered thruster redundancy group is also included, connected to the directly powered groups via DC interconnections. A power management system controls and allocates power from the main switchboards based on power consumption data received from the thruster redundancy groups.

Furthermore, the power supply system features auxiliary equipment connected through inverters, an energy storage system, and a balancing mechanism for power consumption among the main redundancy groups. The system is designed to ensure reliable and efficient power distribution for marine thruster systems, with a focus on redundancy and control. By utilizing a combination of directly and indirectly powered thruster redundancy groups, along with a sophisticated power management system, the patent aims to enhance the stability and performance of marine power supply systems in demanding operational environments.
