SVPWM, three-level indirect matrix converter, unified rotation, Matlab, simplified strategy
According to the disadvantages of the traditional three-level space vector pulse width modulation （SVP- WM） algorithm with a large amount of computation and poor real time, a simplified SVPWM algorithm based on rota- tion and unified processing of reference voltage is proposed, and it is applied to the three-level indirect matrix convert- er （TLIMC）. The method judges the big sector of the output reference voltage and unifies rotation to the first sector, then judges the small triangle area, and optimizes the function time of the vector to reduce the amount of computation to the original 1/6, which is more suitable for digital signal processor program. Finally, the TLIMC simulation model of Matlab/Simulink is constructed, and the simulation results prove the feasibility of the simplified method.
