摘要
日益增多的数据处理系统,如计算机、通信设备等需要高可靠的不间断电源(UPS)。静止型晶体管UPS已广泛应用于20～200kVA。本文综述有关静止型UPS的国外发展动向的若干专题,从一个侧面介绍高频化的新型UPS,微处理器控制的UPS,滑模控制在UPS中的应用以及为使UPS失真度(THD)最小的新策略等。
Today an ever-increasing number of data processing systems such as com-puters,communication apparatuses etc.needs a high reliable uninterruptiblepower supply (UPS). The static transistorized UPS has been extensively employed from 20 to 200kVA.Some special topics concerning the state of arts of the static UPS arepresented,such as:Noval UPS by using high frequency link,micro-processorbased UPS,application of the sliding-mode control in UPS and a new strategyfor minimizing the total harmonic distortion (THD) of the UPS,etc.
