| Abstract: | The main drive system of synchronous motor for Anyang Steel Steckel mill was introduced. This drive system contains a new great power IEGT (injection enhanced gate transistor) converter and inverter. The fixed 5 pulse allocation PWM technology for eliminating high harmonic waves is used. An active current controller and a reactive current controller are respectively designed,which can hold the output voltage of the IEGT inverter while controlling motor current. Compared the GTO inverter,it has a few of char... |
