Case Studies
Current controller for inductive control in the steel industry
Initial situation
The current regulator was developed for a well-known customer in the steel industry in Germany. This current controller is used to precisely control the electrical current in inductive control systems used in the steel industry. It enables optimal power regulation and thus contributes to increased efficiency and quality assurance in steel processing production.
