固体可调速交流传动技术是二十世纪六十年代中问世的。从那时以来,器件、电路、控制原理和信号处理电子设备方面的许多革新大大促进了这项技术。继承以往的经验,推测现有的发展趋势,估计可调速交流传动几乎肯定会在本世纪八十年代前在工业中找到广泛的用途。 本文评述交流传动技术的现状,讨论交流电机,变流器、控制设备的突出技术特点及集成化的传动系统的性能,并指出此技术相应的发展趋势。
Solid adjustable speed AC drive technology came out in the sixties of the twentieth century. Since then, many innovations in devices, circuits, control concepts, and signal processing electronics have contributed significantly to this technology. Inheriting past experience and speculating on current trends, it is estimated that AC speed adjustable drives will almost certainly find a wide range of uses in industry by the 1980s. This article reviews the current status of AC drive technology, discussing the outstanding technical features of AC motors, converters, and control equipment and the performance of integrated drive systems. The corresponding development trends of this technology are also pointed out.
