ABSTRACT:
An electric power source device for electrolytical production or coloring of alumilite, wherein pulses are generated at a predetermined phase of A.C. source, the pulses are frequency-divided by a non-contact circuit and, depending on the results of the frequency division, analogue switches respectively comprising a non-contact circuit are driven to actuate rectifier units for rectifying the A.C. source. Outputs of alternately reversed polarities with distinctly sharp rising and falling are provided.
