Abstract
In order to achieve equivalent modulation of the three-phase five-level current source converter, this paper, based on the topology of three-phase five-level current-source converter, proposes a new method to realize the output characteristic of SVPWM with CBPWM, and this method can be applied in any space vector modulation sector of the topology. Different from the strategies of traditional unity theory, the proposed method decomposes the modulated waves directly according to the switching states of SVPWM in five-level current source converters and compare the sub-modulation waves with two inverting carriers. Finally, a simulation on MATLAB is carried out to verify the correction of the method.
