  • Electrical device for impeding corrosion
    Patent number: 7901547
    Abstract: The present invention relates to an electrical device for impeding corrosion of a metal body. The electrical device includes a driver circuit including at least one inductive component. The driver circuit is suitable for driving one or more pads coupled to the metal body so that corrosion of the metal body is impeded. A control circuit is provided for controlling the operation of the driver circuit. A feedback circuit provides feedback from the driver circuit to the control circuit. The driver circuit can operate as a resonant circuit, owing to the at least one inductive component, and ballast energy applied to the pads.
