摘要
本文论述了UPS的基本技术要求,提出了一种基于数字信号处理器(DSP TMS320F240)的全数字化系统设计方案,并对其中的一些关键问题进行了分析。其中着重详细分析了数字化控制UPS锁相环的原理与性能,提出了一种用于电网电压快速检测和旁路切换控制的方案,以保证UPS能不间断对负载供电。实验结果表明,该方案设计简便、实用性强,UPS可以很好地达到性能指标的要求。
Uninterruptible Power Supply (UPS) has been applied in many fields. The designing purpose of UPS is introduced in this paper. Based on the analysis of some pivotal techniques for UPS, a novel scheme of fully digitized control system based on DSP (TMS320F240) is proposed. The principle and performance of phase lock loop are especially analyzed and the method used for fast voltage detection is presented for the digital- controlled UPS, which are used for supplying the load uninterruptedly. These methods are very simple and practical. The experimental results demonstrated that the practical system could achieve good dynamic and static performances.
