Experimental studies on a single-phase improved switched inductor Z-source inverter

This paper presents an experimental work on improved SL Z-source inverter topology. Because of the limitations of classical Z-source inverter, the SL Z-source inverter has been proposed to increase the voltage gain and to reduce the voltage stress on the capacitors of the Z-network. The simulation and experimental results show that the improved SL Z-source inverter increases the boost factor, improves the voltage stress across the capacitors, and reduces the inrush current.
