| Abstract: | Aim to the problem of the short circuit and non-linearity distortion of output voltage under low voltage transfer ratio,3-zero vector modulation was proposed and the corresponding control system was built with the DSP and FPGA.The feasibility and validity of the method presented was tested by experiment.The output voltage waveform can be improved under low voltage transfer ratio and the operation performance of the matrix converter also become well because of this strategy. |
