POWER SUPPLY FOR ELECTROCHEMICAL TREATMENT OF MATERIALS Russian patent published in 2012 - IPC B23H3/02 B23H7/16 

FIELD: electricity.

SUBSTANCE: invention relates to switch-mode power supplies for electrochemical treatment. The power supply is designed as represented by in-parallel current generators, each connected to the load via the current selector so that to enable the current generator closing while the generator current has not yet reached the value preset or if it is necessary to make a pause between the pulses and the load current selector for creation of a preset duration pulse on the load, such pulse current selector connected to the current generator output so that the normally closed contact is connected to the point in common, the total internal inductance of the current generator and the conductor connecting the current generator to the current selector considerably in excess of that of the total inductance of the load and the conductors connecting the current selector to the load. Transistors protected against puncture with voltage limiters are used as the current selector normally closed and normally open contacts.

EFFECT: invention allows to enhance the power supply reliability due to connection of the current selector normally open contact to current generator via a diode as well as to create a design space-effective and adapted to streamline production due to a common control system and a common voltage limiter.
