Abstract
The installation, for application in electro-deposition of metals, consists of a main current rectifier connected in anti-parallel with another current rectifier so as to produce a wave form with periodic and brief reversions of polarity. A control circuit determines the frequency, duration and amplitude of the negative waves, and an interconnected blocking circuit peridocally excludes the main rectifier for pre-set times during emission of the reverse polarity waves by the other rectifier.
