Abstract
The Z-source/quasi-Z-source inverter (ZSI/qZSI), so called impedance source inverter, has attracted increasing interests due to a single-stage power conversion with step up/down function, handling the DC voltage variations in a wide range without overrating the inverter, and allowing the switches on the same bridge leg turn on together. All of these can minimize system cost, reduce component count and cost, and improve system reliability. The operation principle and control methods of conventional ZSI/qZSI are presented. Also, the advantages and control of novel extended topologies, such as qZSI with Battery and qZSI based cascade multilevel systems are discussed. Impedance parameter design is addressed in detailed. This chapter offers a comprehensive and systematic reference for the future development of the high performance ZSI/qZSI.
