Abstract
A smoothing device for a power supply is provided comprising a rectifier for rectifying an output of an alternating current power supply and at least a pair of electrolytic capacitors for smoothing an output of said rectifier. The pair of electrolytic capacitors have a non-polarized structure in which a pair of electrode foils each having an oxide film on a surface are wound into a roll with a separator containing an electrolyte interposed therebetween. A pair of electrodes are connected to each of said pair of electrode foils. At least one of the pair of electrodes has a mark for distinguishing them from each other. The pair of electrolytic capacitors are so connected that magnetic fluxes generated by said electrode foils are cancelled with each other.

A smoothing device for a power supply comprising:
- a rectifier for rectifying an output of an alternating current power supply;
- and
- at least a pair of electrolytic capacitors for smoothing an output of said rectifier;
- each of said pair of electrolytic capacitors having a non-polarized structure in which a pair of electrode foils each having an oxide film on a surface are wound into a roller with a separator interposed therebetween and with a pair of electrodes being connected to said pair of electrode foils, respectively, said separator being of an ion permeable material and containing an electrolyte;
- at least one of said pair of electrodes having a mark for distinguishing them from each other;
- and
- said pair of electrolytic capacitors being so connected to each other that a magnetic flux generated by said electrode foils in one of said pair of electrolytic capacitors is cancelled by another magnetic flux generated by said electrode foils in the other of said pair of electrolytic capacitors.
