The Onboard DC Grid™ is a step forward in optimized propulsion and is an extension of multiple DC links that already exist in propulsion and thruster drives. Onboard DC Grid enables us to combine the advantage of AC components with a new smart DC distribution.
Just as variable speed drive allows the electric propulsion motors to be run at their optimum working point, Onboard DC Grid™ allows the diesel engines to run at variable speed for top fuel efficiency at each load level. And, the Onboard DC Grid™ enables full flexibility in combining energy sources, including renewables.
