Abstract

Impedance source inverters (ZSIs) have attracted much attention in recent years due to their ability to behave as boost/buck at their output terminals without the need of an extra dc/dc converter to accomplish this task. But the losses can be highly significant if the inverter operates at low voltage levels using devices such as the IGBT semiconductors. This work presents a simple solution to reduce the losses during the shoot-through state of an IGBT-based single phase impedance source inverter. Experimental results demonstrate the effectiveness of the proposed method in reducing the losses by increasing the overall efficiency of the inverter.
