【Abstract】 The harmonic sources tend to threaten the normal operation of power grids.Based on the analysis of the harmonic sources and the methods of compensation,a new filtering measure,active power filter(APF) is presented,including its working principle and internal structure.With an excellent filtering performance,the APF can be used to reduce harmonic pollution and improve power quality.更多还原
