| Abstract: | The work principle of multilevel converter based on cells cascaded was introduced.And then some typical multilevel carrier arithmetics were analyzed and summarized.The building of system module and simulating of these arithmetic was done by MATLAB software.Then their performance was analyzed and compared.The results show that multilevel carrier arithmetic can efficiently reduce common-mode voltage,harmonic and the changing rate of output voltage.These are helpful for selecting the arithmetic of the cells cascaded converter. |
