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.
