现代的交流(交-直-交)电力传动技术,自1971年问世以来,在世界范围内已发展成广泛应用于铁路机车和动车的功率传动系统。本文介绍了至今为止采用这种技术的许多种机车和动车,介绍了所用半导体、控制系统和冷却装置性能方面的进步。牵引电动机采用了无壳体结构。利用新的控制方式,可以使整流器和牵引电动机得到更有效的利用。将来会出现性能更好的半导体,从而可以期望进一步降低整流器和控制装置的费用。
Modern AC (AC-DC-AC) power transmission technology, which has been developed worldwide since 1971, has become a power transmission system widely used in railway locomotives and EMUs. This article describes the many types of locomotives and motorcycles that have been used to date, and describes the advances in the performance of semiconductors, control systems and cooling devices used. Traction motor with a shell-free structure. With new control methods, rectifiers and traction motors can be more efficiently utilized. In the future, semiconductors with better performance will appear and further reductions in the cost of rectifiers and control devices can be expected.
