This paper does some theoretical analysis and simulation studies on the most common topologies of Z-source inverter.As we all know,the traditional Z-source inverter has some problems,such as the voltage of the capacitor which belongs to this topology is higher and there is a startup shock,which caused researchers proposed a variety of improved Z-source topologies to solve these problems.Some of these topologies can increase boost capacity,and some can reduce the capacitor voltage.However,these topologies can improve only part of the problems of the traditional Z-source inverter,which leads to that the users are hard to choose which topologies.Faced with this situation,eleven Z-source topologies are analyzed in terms of boost capacity,inductance start-up current,capacitance stress and economy in this paper.Finally,two kinds of promising topologies were gotten.
