Identification of an Effective Control Scheme for Z-source Inverter

This paper presents a comparative analysis of the Z-source inverter with two different control techniques namely the simple boost control and the maximum constant boost control with third harmonic injection. The Z-source inverter has the capability to buck-boost the input voltage without any intermediate boost conversion stage. It utilizes the shoot-through states effectively to boost the input...
