Abstract: In order to enhance reliability and  stability of control system,the EMC becomes an important factor in design of  UPS.Based on the digital UPS design,the authors analyze the sources of EMI.And from the interference source suppression,system grounding,electromagnetic shielding,isolation technology,and rational layout and structure cabling,the EMC design is analyzed.The result shows that the circuit of design is  reliable and stable,and the design has achieved the expected objective.

Key words: UPS, EMC, grounding, shielding, isolation
