Sliding Mode Controller Design for DC-DC Quasi-Z-Source Converter

The main purpose of this research is designing the sliding mode controller for a Quasi-Z-source converter. For this purpose, we first introduce a Quasi-Z-source converter. These converters, similar to the source Z (ZSC) exchangers, are composed of connecting an impedance network to a voltage and a current source. The advantages of comparing the Quasi-Z-source converter with Z source converters are: installing input flow (in the source type voltage), reducing nominal values for I, V circuit (inductance and capacitor), and generating high voltage gain. These advantages have led to use these converters in photovoltaic applications, wind turbines and hybrid electric vehicles. The Quasi-Z-source converter is extracted from the transducer s moderate model and accordingly, the slider mode controller is designed. Finally, the results resembled the accuracy of the controller function for the converter is shown for two different duty cycles.
