| Abstract: | Voltage sag is one of the most serious dynamic power quality problems,especially to those ASD devices widely used in current industry applications.Therefore it attracts the most attention of researchers.Single-phase voltage sag is one of the most frequent problems.In this paper,we briefly introduce the voltage sag problem,and the equipment sensitivity to voltage sag.Then we make some simulation and analysis on the performance of the widely used brushless DC motor driver under different voltage sag situation with MATLIB.Finally we give some advices on how to deal with voltage sag problems. |
