Power Management of Connected Switched Inductor Z-Source Inverter to the Main Grid Based on Adaptive- Sliding Mode Controller

This paper is a combination of direct power control strategy, adaptive - sliding mode controller and motion vector machine modulation. In the sliding mode control, the stability achieves using to fixe states of system on sliding levels. To explain of the adaptive control can obtain this controller must adapt to a controlled system with parameters which vary, or are initially uncertain. It means that the purpose is direct and quickly regulate of DC/AC converters without current loops control. Converter voltage control can be achieved easily in a rotating reference frame and motion vector machine method used to achieve a constant switching frequency. Also, according to the advantages of impedance network inverter, of Switched inductor Z-source inverter has been used to grow up power quality and exchanging. One of these nonlinear control methods is the indirect adaptive controller which is based on the LIAPANOUVE method, providing stability function In the paper, an adaptive- sliding mode controller to control the current of a Switched inductor Z-source inverter in grid-tie mode, under different load conditions and grid voltage changes in grid, is discussed which achieves in Matlab/ Simulink
