This paper presents the concept of using a switched coupled-inductor cell for implementing quasi-Z-source inverters. By replacing one of original inductors found in the classical impedance network by a coupled-inductor, and adding one diode, new single-stage buck-boost inverter with a small count of elements and a high conversion ratio are obtained.
