DEVICE FOR POWER AND AUTOMATIC CONTROL OF OUTPUT CURRENT SYSTEM OF CATHODIC PROTECTION SYSTEM FROM CORROSION OF METAL CONSTRUCTIONS Russian patent published in 2017 - IPC C23F13/04 

FIELD: electricity.

SUBSTANCE: system of cathodic protection from corrosion of the ship's hull comprises a source of reference voltage, the negative output of which is connected to the ship's hull, a reference electrode and an anode, wherein the source of reference voltage is connected to one input of the differential operational amplifier (OA), the second input of which is connected to the reference electrode, and an output is connected to the first input of the measuring OA, the second input of which is connected to an output of the reference voltage phase shifting PWM converter having an input connected with the output of the measuring OA, which outputs are connected through the series-connected capacitor to the primary winding of the high-frequency transformer, the secondary winding is connected in series through a rectifier and a filter connected with the positive terminal to the anodes, and the negative terminal - to the ship's hull.

EFFECT: increasing the stealth of the ship by reducing the ripple of the output current, reducing the overall dimensions and weight of the device.
