本文介绍了一种数字化并联UPS系统,该并联UPS系统基于分散逻辑控制,采用美国TI公司的TMS320F240作为主控芯片,并应用CAN总线技术完成各并联UPS单元之间的,以及各UPS单元与并联系统监控装置的通讯。文中简要说明了该系统的总体结构、基于DSP的控制原理、并联系统监控装置等相关内容。该并联UPS系统的设计具有较强的实用性。
This paper introduces a digital parallel UPS system based on decentralized logic control system using the United States TI’s TMS320F240 as the main control chip, and the application of CAN bus technology to complete the parallel UPS units, as well as the UPS unit and the parallel System monitoring device communication. The article briefly describes the overall structure of the system, based on the DSP control theory, parallel system monitoring devices and other related content. The parallel UPS system design has strong practicality.
