2 An aluminum electrolytic capacitor consists of cathode aluminum foil, capacitor paper (separator), electrolyte, and an aluminum oxide film, which acts as the dielectric, formed on the anode foil surface. A very thin oxide film formed by electrolytic oxidation (formation) offers superior dielectric constant and has rectifying properties.
Aluminum electrolytic capacitors are made of two aluminum foils and a paper soaked in electrolyte. The anode aluminum foil is anodized to form a very thin oxide layer on one side and the unanodized aluminum acts as cathode; the anode and cathode are separated by paper soaked in electrolyte, as shown in Fig. 8.10A and B .

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Some types of capacitors, primarily tantalum and aluminum electrolytic capacitors, as well as some film capacitors have a specified rating value for maximum ripple current. Tantalum electrolytic capacitors with solid manganese dioxide electrolyte are limited by ripple current and generally have the highest ESR ratings in the capacitor family.
Aluminum electrolytic capacitors are comprised of anode and cathode plates separated by an absorbent spacer. As shown in Figure 3, metal tabs are attached to the anode and cathode plates, and the assembly is wound into a cylindrical section. The tabs are welded to aluminum terminals installed in a header (top).
In the higher-power applica-tions discussed in this paper, the input capacitor is usu-ally aluminum electrolytic. This paper will focus on three main capacitor types used in higher-power inverter applications: snapmount, plug-in, and screw-terminal capacitors. See Figure 2 below and Table 1 on page 3.
