Abstract :
The performance of the large power converter system for rolling mills should meet the need of production technology and adapt to the requirement of the electric network. In the paper, the cycloconverter system is introduced. With the development of large power electronics, application of the large power converter using the self-controllable devices such as IGCT and IGBT becomes the trend. The three-level AC-DC-AC converter system with IGCTs whose rated power is 7.5MVA has been developed and put into use. And it is estimated that the AC-DC-AC converter system will be used in the drive for rolling mills in the near future.
