Abstract

Impedance source inverters have attracted much attention in recent years due to their ability to behave as voltage elevators/reducers at their output terminals without the need of an extra dc/dc converter to accomplish this task. Among these inverters, the quasi-impedance source inverter (qZSI) is one of the most known topologies. It considers two basic operating states, the no-shoot-through state (nSTS) and the shoot-through state (STS). One of the major drawbacks of the qZSI is that the STS can present significant power losses mainly due to the voltage drop in the semiconductors that activate this state. This work presents a simple alternative of implementation that allows reducing these losses up to 50% during the STS, thus increasing the overall efficiency of the impedance source inverters. © 2017 IEEE.
