Electrolytic capacitor
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. Because of their very …
Capacitors | Brilliant Math & Science Wiki
Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity …
Ground and neutral
Neutral wires are usually connected at a neutral bus within panelboards or switchboards, and are "bonded" to earth ground at either the electrical service entrance, or at transformers within the system.

Inverter DC Link Capacitor Selection
In a VSI, the DC link capacitor has two main responsibilities – Provide low impedance path for high frequency currents – As frequency goes up, the battery and cable parasitic inductance cause the impedance to increase. The DC link capacitor impedance goes down so it becomes the preferable path for high frequency AC to circulate.

Difference between Line Voltage and Phase Voltage
The line voltage is √3 times the phase voltage in the star connection. Thus, the line voltage is 173 % of the line voltage. Line voltage is more than the phase voltage in the star connection. If the phase voltage is 240 V, then the line voltage will be √3 X 240= 415 volts. 2. Line voltage is the potential difference between two phases.
