    Abstract: A system is submitted here that permits superimposing an alternating current in the process of electrolytic refining of metals based on the use of power semiconductors without requiring an external source and which minimizes the utilization of passive elements, achieving a high efficiency solution applicable to high power industrial processes. The invention consists of the division of the cells involved in the metals electrolysis process in two groups of cells (3a) and 3b, both comprising a similar number of anode-cathode pairings, and with both groups linked by a common point for electrical connection (6), and interconnected by means of a bidirectional power converter (7). Said power converter (7) is connected to the common point for electrical connection 6 of the groups of cells (3a, 3b) and to the other two connection points of each group of cells, so that its operation permits transferring power from one group to the other.
