Ropi is the newest member of our forced air cooled dUdT filter family. Utilizing advanced design concept the overshoot and du/dt requirements can be easily adjusted for optimum operation. It has efficient hotspot elimination and flexible mechanics which together make design very compact. With Ropi you can provide most integrated converter solution. Typical applications for Ropi are e.g. Double Fed wind turbine and motor drive applications.
