Résumé : 

Study of a Solar Photovoltaic Regulator for Cathodic Protection Systems Cathodic protection has divers known industrialapplications in buried or submerged pipes protection. The surrounding environment and the economic aspects are two decisiveparameters in the choice of the method of protection. When theenvironment conditions are well known and the method of protection properly mastered, the cathodic protection is generally cheap and efficient over a long period of time. The photovoltaic conversionrepresents a good issue to provide the needed autonomous energy forseveral applications. Since it has many applications, we are preciselyinterested in cathodic protection one. To well manage the use of thebattery, according to the desired application, it’s necessary to makean adequate choice of the type of the regulator of load. Theprevention opposes to the corrosion of the metallic deep pipes. Thus,a variable exit regulation for cathodic protection is studied. Thestabilization of the PV.G voltage guarantees a load of battery withfixed voltage. The charging current threshold takes into account oftwo parameters; the permanent measurement of the PV.G currentoutput and of the increase in its voltage.
