摘要：

Compared with the three-level converter, five-level converter has the advantages of low harmonic content of output current, good waveform quality of voltage and current, and low switching loss. However, the space vector modulation technology of five-level converter has the problems of many vectors and complex control. To solve this problem, this paper proposes a five-level simplification algorithm based on reference vector translation. This algorithm makes full use of the mature space vector modulation technology of a two-level converter. First, the five-level space vector is simplified to three-level SVPWM modulation, and then the three-level SVPWM modulation is simplified to the two-level SVPWM modulation. And based on MATLAB/Simulink simulation platform and dSPACE hardware in the loop simulation platform, the five-level simplification algorithm is deeply studied. Simulation and experimental results verify the effectiveness of the strategy proposed in this paper.
