Abstract
A corrosion protection device, system, and method are provided. The device may operate while being coupled to the object being protected and to a power source using a total of only two terminals. This may be accomplished by de-referencing the return path node of the circuit using a choke device that blocks a temporal AC component of an anti-corrosion signal. The choke device therefore diverts the anti-corrosion signal to a single negative/ground path to the object and then returns through a positive lead of the circuit. A two terminal corrosion protection device may thereby simplify the installation process, for example on a vehicle, by not requiring that another connection be made to the object at a spaced apart location from a first connection to the object.
