ELECTRIC POWER SUPPLY OF CATHODIC PROTECTION STATION Russian patent published in 2010 - IPC C23F13/02 

FIELD: power industry.

SUBSTANCE: electric power supply of cathodic protection station contains line RF interference filter connected to mains rectifier, active filter the load of which is high-frequency inverter including two commutators, commutation circuit with resonance capacitor and two resonance throttles, which converts constant voltage to high-frequency alternating voltage for power supply of transformer the secondary winding of which is connected to rectifier bridge, output smoothing filter for smoothing of output voltage pulsations, connected to rectifier bridge, controlled with output voltage, additional throttle of high-frequency inverter, which is in-series connected to primary winding of transformer; at that, resonance capacitor, two resonance throttles, additional throttle and primary winding of transformer are made in the form of common integrated electromagnetic component.

EFFECT: decreasing the weight and dimensions of electric power supply of cathodic protection station, reducing the flow of electric insulating and structural materials, and increasing the device efficiency.
