What types of voltages do ships generally use?

Ships utilize a combination of alternating current (AC) and direct current (DC) voltages to meet their diverse electrical needs. The use of AC is common for powering large motors and systems such as lighting, heating, and air conditioning because it is well-suited for distributing power over significant distances. Conversely, DC is often required for specific applications, including electronic devices, control systems, and battery charging, which are integral to a ship's operational functionality.

This hybrid approach allows ships to optimize energy use and ensure that all electrical systems can operate effectively under various conditions and loads. Employing both types of voltages provides flexibility in electrical design and the ability to use different power sources, which is essential in marine environments where reliability is crucial.
