| Abstract: | A real-time frequency tracking method for inverters based on Point-by-Point Analyses technique of LabVIEW was introduced in this paper. The real time tracking of signal frequency was implemented by doing simple and point-by-piont mathematic operation for base wave component acquired. And the feasibility and effectiveness of the method was proved by making a comparison of the other two methods supplied by LabVIEW. |
