| Abstract |
This paper describes a new generation of Drive Control Units (DCU) developed to control the Adtranz IGBT converter family in traction applications. The focus for the application has especially been cost limited mass transit applications, but due to the control boards flexibility it is possible to apply it in simpler loco or two system configurations. The Drive Control Units fit perfectly into the MITRAC Communication & Control world on one hand and the Adtranz IGBT converter family on the other hand. It is possible to configure the DCU by means of software for the application with both DC and AC supply systems as line converter control unit, motor converter control unit, or auxiliary converter control unit. An optimization regarding reliability, availability, and maintainability (RAM) has been performed and special care has been taken to fulfill the safety case requirements which become more and more important. Other not less important design aspects have been commissioning and diagnosis. |
