Abstract

Advances in transportation systems have been spectacular. A variable-voltage variable-frequency (VVVF) inverter drive, which applies a large-capacity gate turn-off (GTO) thyristor and a high voltage insulated gate bipolar transistor (IGBT) have been developed to attain higher speed, lighter weight and lower level of noise of transportation systems such as rolling stock, elevators and electric vehicles. In view of the above-mentioned needs, Hitachi has propelled research and development not only to improve individual component devices employing sophisticated power electronics and microcomputer technology, but also to maximize the performance and minimize the size, weight, and level of noise of conventional transportation controllers. In transportation systems, the inverter control is already becoming mainstream. In this light, Hitachi has tackled the development of large-capacity GTO thyristors, high voltage IGBTs, GTO and IGBT drive technology, cooling technology and installation technology. This paper describes Hitachi's role in the area of power electronics for transportation. Especially, new systems of rolling stock are explained.<>

日立在交通运输电力电子领域的作用

交通运输系统的进步是惊人的。为了实现铁路车辆、电梯、电动汽车等交通运输系统的高速度、轻质量和低噪声，研制了一种采用大容量栅关断(GTO)晶闸管和高压绝缘栅双极晶体管(IGBT)的变压变频(VVVF)变频器。鉴于上述需求，日立推动了研究和开发，不仅采用先进的电力电子和微型计算机技术来改进单个组件设备，而且还最大限度地提高了传统运输控制器的性能，最大限度地减少了尺寸、重量和噪音水平。在交通系统中，逆变控制已经成为主流。有鉴于此，日立已着手开发大容量GTO晶闸管、高压IGBT、GTO和IGBT驱动技术、冷却技术和安装技术。本文介绍了日立在交通运输电力电子领域的作用。特别介绍了机车车辆的新系统。
