Identification of an Effective Control Scheme for Z-source Inverter
نویسندگان
چکیده
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 voltage. A model of the Z-source inverter is built in MATLAB/SIMULINK and its performance is analyzed with the two control schemes. The effective scheme is identified based on the current and voltage waveforms, voltage gain and voltage stress. The experimental result on a prototype inverter validates the simulation results.
