Study of an Intelligent Capacitive Load Switch Used on Reactive Power Compensation

The design method of new capacitive load switch,which integrated the advantages of pulse switch and thyristor,was proposed.The timing sequence between the pulse switch and thyristor was set up.The synchronous sampling of multi-channel power signals and the control of capacitive load switch were realized based on ARM9 and Linux operating system.In addition,the algorithm based on fuzzy control theory was used to improve the switching reliability.
