Bridges, ships and offshore wind turbines are three examples where the prevention of corrosion of the structure is very important and greatly reduces operating costs.
Passive corrosion control.
For environmental reasons, the traditional passive ‘sacrificial anode’ method of corrosion control is increasingly being replaced in favour of active prevention, which is implemented by applying an ‘impressed current’.
Active corrosion control.
In the passive method, the anode of a different metal to the structure is ‘sacrificed’ in order to ensure that the structure is protected from corrosion. In the active method, a sophisticated electronic current control system is used to inject a reverse current to that generated from corrosion to protect the structure. Since current flow is closely related to the flow of charge over time, having constant current control allows the user to accurately control the process.
High efficiency and the ability to control current and voltage across the broadest possible range are the main characteristics required for power supplies deployed in active corrosion control. TDK-Lambda has developed several constant current power supply solutions – the ZUP, Z+ and Genesys – that allow full control of the current and the output voltage, as well as feedback on the same parameters.
The availability of isolated interfaces, analog, digital RS232/485, IEEE488 and LAN allows a high flexibility of integration and system control. Power ratings range from 200 W to 15 kW, with the possibility of placing up to 4 units in parallel to increase the power up to 60 kW and output currents up to 4000 A. In addition, the company can optimise a standard product or even develop a custom solution to meet the needs of a particular user application.
