A high-performance, controlled cycloconverter for traction power application

The application and performance of a cycloconverter-type frequency converter as applied to traction (railroad) power loads are discussed. The following items are detailed: the basic theory and operation of a cycloconverter and traction power, ratings to meet performance requirements for traction application, efficiency and power factors, harmonic analysis, and a summation, including the advantages of static frequency conversion equipment. The data contained are based on corroborated experimental results from the field installation of a 3-15 MVA static frequency converter station.<<ETX>>
