Simulation Research on Shoot-Through-Segment SVPWM of Three Phase Z Source Inverter

As an improved algorithm based on traditional SVPWM modulation,shoot-through-segment SVPWM has not been described in detail in paper so far.This paper firstly introduces the working principle and topology of the three phase Z source inverter.Then,based on the modulation principle and algorithm implementation and simulation of the traditional SVPWM,the corresponding changes are made to illustrate the principle of the shootthrough-segment SVPWM,and the simulation model is built by using the modules in the Simulink toolbox of MATLAB software.Finally,the simulation model is built by combining it with the three-phase Z source inverter.By analyzing the simulation results,the validity of the shoot-through-segment SVPWM modulation algorithm and the simulation model are verified,which provides a reliable reference for the relevant learners and users.
