Title:
FILM CAPACITOR, CONNECTED-TYPE CAPACITOR, INVERTER, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/021417
Kind Code:
A1
Abstract:
This film capacitor comprises a wound dielectric film 1, a main body part 3 having a metal film 2 disposed on one surface of the dielectric film 1, and external electrodes 4 respectively provided at a pair of end sections located in the axial length direction of the main body part 3. When the surface roughness of the metal film 2 in the width direction of the dielectric film 1 is set as S1 and the surface roughness of the metal film 2 in the length direction of the dielectric film 1 is set as S2, S1 and S2 have the relationship of S1 > S2 and the average value of the fractal dimension of a boundary line of unevenness due to wrinkling of the metal film 2 is 1.08 or more.
