A Variable Speed Drive () for subsea installations (), subsea vessels or subsea vehicles, as well as to a corresponding subsea installation (), subsea vessel or subsea vehicle, has an alternating current/alternating current converter () having a current-controlled capacitor-less direct current link ().

Variable speed drive for subsea installations, vessels, and/or vehicles

A capacitor () for application in high pressure environments has at least two electrodes () and at least one electrically insulating film () forming a dielectric between the electrodes (), each electrode () having at least one metallic foil () or at least one metallic layer on the electrically insulating film (), wherein the capacitor () is unencapsulated and designed to allow a surrounding liquid to fill cavities of the capacitor (). Furthermore, an electric device has at least one such capacitor () in a device housing, whereby the device housing is filled with an electrically insulating liquid.

Capacitor for application in high pressure environments

An electronic component () for application in high pressure environments has a casing () entirely filled with an electrically insulating first fluid (F), whereby the casing () exhibits or connects to a volume compensation unit for compensating a volume change of the first fluid (F). An electric device () has at least one such electronic component () in a device housing (), whereby the device housing () is filled with a second fluid (F).
