ASYMMETRIC CURRENT OBTAINING DEVICE Russian patent published in 2011 - IPC H02M9/06 

FIELD: electricity.

SUBSTANCE: proposed asymmetric current obtaining device includes controlled direct and return current power supplies of electrolysis unit, which are connected to current switch of electrolysis unit, control unit of current switch of electrolysis unit, which is connected to electrodes of electrolysis unit, electrolysis unit for cleaning of waste water and group of sensors of controlled waste water cleaning parameters. According to the invention, controlled direct and return current power supplies of electrolysis unit are made in the form of pulse current converters, and current switch of electrolysis unit is made in the form of key current inverter on semiconductor devices. Besides, the proposed device is equipped with computer connected to group of sensors of controlled waste water cleaning parameters and control unit of current switch of electrolysis unit.

EFFECT: increasing operational life of the device and possibility of automation of cleaning process of waste water from process impurities.
