Abstract
A marine propulsion system includes an electric marine drive comprising an electric motor powered by a power storage system, a link capacitor connected to the electric motor in parallel with the power storage system, and a high current switch positioned in a main current path between the power storage system and the electric motor and configured to have an on state that allows sufficient current to flow from the power storage system to power the electric motor and an off state that blocks bidirectional current flow along the main current path. A current limiting circuit is positioned in parallel with the high current switch and is configured to provide a controlled current to charge the link capacitor while the high current switch remains in the off state and may also be configured to control current flow from the link capacitor to the power storage system to recover power from the link capacitor while the high current switch remains in the off state.
