© 2018 IEEE. This paper introduces a closed-loop small-signal model of current-mode controlled A-source converter. The A-source converter is a magnetically-coupled, impedance-source, high voltage-boost converter for dc-ac and dc-dc applications. Derivation of closed-loop inner current loop and its transfer functions are discussed in detail. Moreover, both frequency and transient performances of the closed-loop current-mode controlled A-source converter have been verified by computer simulations using MATLAB and SABER circuit simulator. In addition, a laboratory prototype has been built to verify the theoretical analysis.
