Converter systems

We offer a whole construction line of the second-generation performance semiconductor converters MODULEX, VARIANT, COMPACT and INVERT. The conceptual solution of these systems allows for the creation of small, medium and large output semiconductor converters up to 35 kV. The foundations of the converter systems are replaceable blocks with semiconductor components and air coolers working on the basis of heat pipes. This modern semiconductor cooling system helps to significantly lower converter mass as well as dimensions, compared to traditional cooling.


Optic conductors, which significantly increase the reliability and resistance of the converters to interference, are used for control signals on high voltage converters. The converter construction enables the highly flexible replacement of power performance semiconductor blocks as needed.
