| Abstract: | Frequency convertors are widely applied in the driving field. How to appropriately select the frequency convertors is comprehensively analyzed and introduced, including the understanding of the inversion elements of the frequency convertor, topological circuit, the control mode of the frequency convertor on the driving motor and the load-torque characteristic, etc. In the application of frequency convertors, it should be considered that there are harmonics in the input and output current and the relevant ma... |
