Medium voltage components for power electronics Does this sound familiar? Voltage increases, whenever it is least expected. Good for thrillers. Not so good for power electronic installations. That is why we developed our “ready-to-use switch components” based on IGBT and Thyristor technology, specifically for use in MV applications. They are even available with or without control or current loop feed power supply. So sit back, relax and look forward to an exciting conversation with your House of Competence. It's worth it.
