Abstract
Corrosion protection is provided to a metallic structure by a sacrificial anode system. A current control element is used to achieve fast and adequate corrosion protection under changing conditions, while excess current flow is minimized to extend anode life and avoid overprotection. The basic advantages of sacrificial anode systems such as simplicity and autonomy are retained. The system employs a field effect or a MOS (metal oxide silicon) semiconductor device to act as the current control element.
