Abstract This paper presents a new family of high boost gain single stage inverters, namely switched coupled inductor quasi-Z-source inverter(SCL-qZSI). The basic topology is known in the literature as quasi-Z-source inverters(qZSI). In comparison to the switched coupled inductor Z-source inverter(SCL-ZSI), SCL-qZSI shows some merits on the same input and output conditions, including continuous input current, a common ground with the dc source, reduced passive component count, and reduced voltage stress on capacitors. This paper presents the operating principles, analysis, and compares them to these of the SCL-ZSI. To verify the performance of the proposed converter, a laboratory prototype was constructed, and the experimental results under the simple boost control method are shown to verify the correctness and effectiveness.

Key words： Quasi-Z-source inverter high boost ability coupled inductor shoot-through zero state
