Dynamic Modeling and Analysis of $Z$ Source Converter—Derivation of AC Small Signal Model and Design-Oriented Analysis

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper contributes to the ac small signal modeling and analysis of <formula><tex>$Z$</tex></formula> source converter (ZSC) in continuous conduction mode. The ac small signal model considers the dynamics introduced by <formula><tex>$Z$</tex></formula> network uniquely contained in ZSC. AC small signal model of ZSC is derived and computer simulation results are used to validate the small signal modeling method. Various applications of the ac small signal models to ZSC design and experimental verifications are presented. </para>
