transmitting electrical energy. isibly very different due to their Vmuch smaller size and cylindrical design, the new dry capacitors are al-ready making their mark in commercial use, for example in the DC links of high-voltage DC (HVDC) installations, where they stabilize DC transmission voltages ranging from 9 kV to 150 kV.
A look at how capacitors have developed from ‘wet to dry’ helps to explain the importance of the new technology. The smaller, the better. ABB’s new dry capacitor conventional capacitor of the same rating. Metalized capacitor film (left), showing typical segmentation. The size of the segments is about 1 cm2.

The cathode in a wet Aluminum electrolytic capacitor The cathode consists of an Al foil that formerly was plain but now has a certain degree of etching and subsequent surface magnification.
An electrolytic capacitor is a polarized capacitor whose anode is a positive plate where an 95 oxide layer is formed through electrochemical principles that limit the use of reverse voltage.
Solid electrolyte – conductive polymer is applied in thin layer on anode, cathode and paper foil in order to improve ESR and conductivity. The structure is then dipped into a liquid electrolyte as in the case of standard wet electrolytic capacitors. See Figure C3-7a. Figure 8. Schematic of hybrid Al electrolytic capacitors
The liquid or “wet” electrolyte solution in the majority of wet tantalum capacitors is a sulfuric acid solution. A suitable end seal arrangement prevents the loss of the electrolyte . Wet tantalum capacitors have several advantages over solid tantalum, aluminum electrolytic, and ceramic capacitors.
