Abstract :
Compared to previous Z-source inverter topology, improved Z-source inverter has advantages such as low Z-source capacitor voltage stress and inherent inrush current limitation. This paper investigates the third harmonic injection control strategy of improved Z-source inverter. Compared to simple boost control, it can reduce the voltage stress and Z-source inductor current ripple. Theoretical analysis, simulation and experimental results were presented to demonstrate the features of the control.
