An Analytical Approach for Fractional-Order Modeling and Analysis of Z-Source Converter

This paper contributes to establish the fractionalorder mathematical model of the Z-source converter (ZSC) in continuous conduction mode which is different from the conventional integer-order ZSC case. The corresponding theoretical analysis of the fractional order ZSC based on the equivalent small parameter method (ESPM) and the derivation of the fractional-order transfer functions of the system are presented, respectively. Finally, simulation results are presented to demonstrate the correctness of the fractional-order model and the validity of the proposed theoretical analysis.
