专门为货物搬运装置的驱动系统设计的新型半导体器件

New Power Electronic Components for Materials Handing Drive Systems

升降机和其它一些货物搬运装置的驱动方式有很多:它们为搬动货物提供了机械能-如作为吊车的水力泵和推进器的马达-也有作为辅助性驱动装置的-如方向盘。如果这些能量都是由自带的电池供应的,这些驱动就会包括一个由变换器控制的电动机。下面将讲述专门为这些变换器设计的新型的功率半导体器件。关于它们的一些特性将围绕着货运搬运装置的一些特殊要求进行,另外也会讲述一下驱动部分逆变器的结构。

There is variety of drives in lift trucks and other materials handing equipment： They supply the mechanical energy to move the materials-such as the motors for hydraulic pump or propulsion of a fork lift truck-and are further used as auxiliary actuators-e. g for steering. If the operating energy is stored on board in a battery, those drives consist of electric machines, being fed by a converter. The following considerations deal with a new series of power semiconductor components designed for in this kind of converters. Their basic characteristics are discussed with special regard to the requirements in materials handing equipment, additionally some setups of drive inverters are proposed.
