Summary:This paper briefly describes the topology of a quasi-Z source inverter. According to the application of the actual situation, an improved PWM technology is proposed in this paper, and a brief analysis of the improved PWM technology is made. In this paper, the traditional maximum boost SPWM control technology is improved, combined with the three-phase waveform, reducing the current harmonic distortion rate. This system allows the maximum boost SPWM control technique to be applied to systems with unstable input voltages. The simulation model is built by MATLAB software Simulink library. The simulation results prove the correctness of the model.
