Performance Analysis of Dual Loop Z-Source Inverter

This paper presents a performance analysis of dual loop z-source inverter (ZSI). Z-source inverter is controlled by dual loop control strategy. Such as outer voltage loop and inner current loop are taken into consideration. The peak dc-link voltage is estimated by measuring both the input and capacitor voltages. Many Pulse Width Modulation (PWM) techniques are analyzed for the conversion among that it has been proven that Maximum Constant Boost Control PWM is a best method. Maximum constant boost control method is used to produce the shoot through states (ST).With this proposed method distortion in output voltage and stress in switch can be reduced. A high performance language for technical computing MATLAB is used here to implement the concept.
