Abstract: On the basis of the switched-inductor Z-Source inverter, this paper proposes a new switched-inductor Z-source inverter topology with high boost voltage, which is totally different from any other existing Z-source inverters from the viewpoint of circuit structures and operating principles. This new topology not only retains the basic X-shape structure, but also can exchange the position between diode and inverter bridge by adding two inductors and six diodes. It excels at reducing the voltage stress and increasing the peak dc-link voltage, meanwhile ensuring the continuity of the input current; moreover, it can be controlled simply by adopting the boost control, which is also well known in the traditional switched-inductor Z-source inverter. That is to say, it uses the sine wave as the modulation wave, and the triangle wave as the carrier wave. The method is based on the sinusoidal pulse width modulation control technology. When the triangular carrier wave amplitude is greater than the sine wave's peak value or conversely less than the sine wave's negative peak value, the three-phase bridge arms of the inverter was straight at the same time.
