Novel & Practical Digital Parallel UPS System Based on CAN_BUS

Abstract

The novel & practical digital parallel UPS system has been introduced in this paper. The parallel UPS system bases on distributed logic paralleling control strategy used by TMS320F240 as main-control chip. Data communication is realized among all of parallel UPS units or between parallel UPS units and supervision device with application of CAN bus technology. This paper illustrates briefly relevant content such as the total frame of parallel UPS system, control principle based on DSP, the design of parallel supervision device, and so on. The design of the parallel UPS system has advantage of high practicality
