instead of a commonly used structure of planar capacitor, in this paper a cylindrical capacitor
structure with digitated electrodes for both the stator and rotor has been implemented.
The negative potential over the rods causes the total charge as follows, when the geometry is considered as a cylindrical capacitor
To develop the fiber, the researchers roll conducting and insulating polymer films around a copper wire to create a 2 cm-wide cylindrical capacitor
. The cylinder is heated to 200"C and stretched until it is a soft elastic fiber 0.9 mm in diameter.
These changes meant that one of the large cylindrical capacitors
on the main board also had to be moved.
Featured capacitors will include Vishay metallized polypropylene film capacitors for DC-link applications; aluminum electrolytic capacitors with ultra-long life; Vishay ESTA cylindrical capacitors
for power electronics (PEC); single- and three-phase power factor correction (PFC) capacitors; and environmentally friendly X1, X2, and series impedance capacitors for severe ambient conditions.
