Abstract
A multilevel converter includes at least one converting unit, where the converting unit includes N interleaved parallel bridge arms which enable the converting unit to output 2[(M−1×)N]+1 level signals, where N is an integer greater than or equal to 3, M is the number of levels received by the converting unit, and M is an integer greater than or equal to 3; a direct current inputting unit that supplies the direct current to the converting unit; a voltage dividing unit, where an input end of the voltage dividing unit is connected to an output of the direct current inputting unit, and an output end of the voltage dividing unit is connected to an input end of the converting unit; and at least one filtering unit, where the filtering unit is connected to the converting unit to output an alternating current.
