Which component is NOT typically included in an electric propulsion system?

Capacitors are typically not included as a primary component in an electric propulsion system. In an electric propulsion setup, the main components include inverters, which convert direct current (DC) to alternating current (AC) for the electric motors, and generators, which produce electricity to power the system or charge batteries. Electric propulsion motors, of course, are the core element responsible for converting electrical energy into mechanical energy to drive the vessel.

While capacitors have their applications in electrical systems—such as smoothing out voltage spikes or providing temporary bursts of power—they do not serve as a fundamental component specifically in electric propulsion systems. They are more commonly associated with power quality and energy storage in different contexts, rather than as integral elements that facilitate the propulsion of the vessel itself. Thus, the inclusion of capacitors in a typical electric propulsion system would not align with the essential components designated for that specific function.
