Three Phase Z-Source Rectifier

This paper makes the research on an impedance-source rectifier (abbreviated as Z-source rectifier), describes the operating principle, operating modes, and its concept and superiority. Analysis and simulation results show that the three-phase Z-source rectifier can buck-boost voltage by using the shoot-through state, which is harmful for the conventional VSR. It needs small dc-link inductor L and capacitor C, and makes the input unity power factor become possible without any additional circuits, minimize component count, and increase efficiency
