摘要
Abstract
A medium-voltage and high-power convertor with IGCT was introduced.Its single power rating could reach 8 MV·A,and a few convertors could be paralleled together in order to drive a higher-power load.AC-DC-AC and back-to-back topology was adopted,the rectifier and inverter had the same power units—three level NPC connected into DC-link.The rectifier was designed with AFE so that the energy from DC-link could feed to the power grid.The rotor flux orientation vector control strategy,which ensured the highest torque quality,was applied in the inverter.So, the convertor shows an excellent drive system efficiency including low harmonic content and high speed performance, and is appropriate for a wide-range variable-speed drive system.关键词
