Modern control and power electronics for the AC drives of the German high-speed train ICE

摘要

On May 1, 1988, when the ICE/V high-speed experimental train of the German Federal Railways (DB) reached the world record speed of 406.9 km/h, it was the first time that the public at large was presented with the future train in high-speed rail traffic. The electric traction equipment of such a forward looking means of traffic must logically represent the latest state of the art. Two development trends in particular characterize the technology. The first is the use of microprocessors for the complete control of the traction system and the second is the use of GTO thyristors for the converters. Siemens innovated the drive system taken from the class BR 120 locomotive of DB for the ICE/V by the development of a microcomputer traction control and a GTO converter. The microcomputer traction control is used for all 82 series power cars, the GTO converters will be provided for the second half of the series power cars.
