| Abstract |
In Russia, railways work with some AC and DC contact voltages, including 3 kV DC. This paper examines the design work of an auxiliary converter with large power (235 kW) on the trade-off procedure. A solution suggests a two- and three- sectional variant of the auxiliary power converter (APC) permitting the ability to lower the dimensions of the design, to make a simpler, more reliable and maintainable a high-voltage part. Redundancy has been considered, including one section of an electrical locomotive and between other sections as well. The actions of the APC under strong effects of an input voltage should keep the design with normally operating without damaging any components of a power mesh. Some other important items developing the APC, such as reserve controller, digital filters, and EMI points are also examined. Modeling and experiment results verify an analysis. |
