Modifcation of quasi-Z-source inverter operating in stand-alone power system

摘要

In this article the new modified topology of quasi-Z-source inverter (qZSI) is proposed. Modified qZSI allows a stand-alone power system to operate in idle mode without need connect a ballasting resistor. Time diagrams of voltages and currents of proposed topology simulation are presented. The comparison of characteristics of new topology with characteristics of conventional qZSI was conducted.
