[Abstract]:The level IGCT inverter represents the mainstream development direction of the high performance high power medium voltage drive frequency converter. The independent development of the high performance high power three level IGCT medium voltage drive inverter is carried out, the key technology breakthrough is realized, and the foreign monopoly and technology blockade are broken. To fill in the gaps in domestic technology, to improve the independent supporting capacity of the core equipment systems such as metallurgical rolling mills and ship propulsion, and to reduce reliance on key imported equipment, so as to improve the national industrial system and revitalize the national industry. Ensuring national defense construction is of strategic significance. In this paper, the physical structure and working principle of the inverter's core power component -IGCT are introduced in detail, and the performance of the converter is compared with that of the GTO-IGCT. The technical advantages of the IGCT device in the application of medium-voltage and high-power frequency conversion are described. Secondly, this paper introduces the main circuit structure of 9MW high power middle voltage three level IGCT converter, the composition and working principle of each important electrical component. Then, combined with theoretical calculation and engineering experience, the selection of key components of frequency converter is analyzed, including IGCT components, continuous current diodes, absorption components, DC supporting capacitors. Calculation formula and selection principle of basic parameters of components such as power resistance. The test results show that the main technical specifications of the converter fully meet the requirements of the technical specifications, and the product development is successful. Based on the engineering practice of the inverter, this paper designs a high-power 9MW high-power medium-voltage three-level IGCT converter with full intellectual property rights by combining with the prototype test. And for the future of its new generation of product design and development to provide a reference.
