Abstract

High energy efficiency and increasing the working frequency of the converter will make it possible to minimize the size of the cooling system and reduce energy consumption. Auxiliary converters using the SiC technology are a new quality. The reduction of weight and size is very significant (ca. 40–50%). Higher switching frequency reduces the size of magnetic components (ca. 80%), and higher converter efficiency minimizes the size of the cooling system. The overall efficiency of the converter is extremely high (94–96%). This paper presents comparison of Si and SiC parameters which are important for modern solutions, dedicated for railway traction vehicles. Paper presents also parameters of SiC auxiliary converter, designed and manufactured as state-of-the-art product for modern mainline electric locomotives.
