Abstract
Aiming at the application range of Z-source inverter, an enhanced switched inductor quasi Z-source inverter with high boost capability is proposed in this paper. By applying the switched inductor cascade technology to the switched inductor Z-source inverter and transforming its structure, It has higher boost capacity, lower capacitor voltage stress and certain ability to suppress start-up impact, so as to further strengthen the circuit stability. The working principle of the inverter proposed in this paper is analyzed and its performance is compared. In the aspect of control, space vector pulse width modulation (SVPWM) technology is used to control it without increasing the number of switching actions. Matlab / Simulink software is used to simulate the proposed inverter to ensure its correctness and feasibility. Finally, the inverter is further verified by building an experimental platform.
