“…In higher powers, the difference would be more sensible, and the lower current stress of the switches in the proposed converter can play an important role in cost reduction. In addition, the three-phase configuration has been assumed for all the inverters (some of them have been presented in single-phase form as in previous articles 16,22 ).…”

Summary In this paper, a new combined impedance‐source network inverter (CISI) with high voltage gain in low duty cycle is presented. With common ground between the input source and the inverter bridge and a continuous input current, the proposed converter is a suitable choice for renewable energy applications. The duty cycle of the inverter switches is low, leading to a reduction in losses and improving the efficiency. Also, due to the small duty cycle, the modulation index can be increased, and as a result, the quality of output voltages and currents is greatly improved. The proposed circuit has no switch in the input impedance network, and the number of components is reasonable compared to other works. Another advantage of the proposed converter is the low voltage stress on its capacitors and diodes. The proposed circuit is designed and tested at 180 W. The experimental results and the calculated values are close to each other, verifying the accuracy of the analysis.

“…Different indicators are considered to evaluate these converters according to their type and application, including the number of elements, current and voltage stress on the components, the current ripple input and output voltage ripple, the operating range for different duty cycles (D), and so on. In this regard, the most essential feature of ZSI is the amount of increase or decrease in input voltage, because of which different structures have been developed for them [10–39]. By changing the traditional ZSI structure, qZSI [10], improved ZSI (IZSI) [11], inductor ZSI (L‐ZSI) [16], and switched‐inductor‐capacitor ZSI (LC‐ZSI) [32] are provided to fix the conventional Z‐source inverter defects.…”

Two structures are proposed based on the quasi Z‐source inverter (qZSI), which can significantly raise the output voltage in applications, including photovoltaic and fuel cells, in which the input voltage is low. The proposed inverters provide a continuous input current and reduce the voltage stress on capacitor. Besides, the proposed switched‐capacitor‐inductor qZSI (SCL‐qZSI) can suppress inrush current at the start up moment as this current might damage the devices. The performance of the proposed structures is investigated at different operating modes, and the voltage equations are calculated. The voltage stress on switches, the voltage stress on capacitors, the voltage stress on diodes, and the current stress on inductor, as well as the average DC‐link current, the gain voltage (G), and the boost factor (B) of the proposed inverters, are analysed and derived. They are then compared with similar converters. To confirm the performance of the proposed converters, a laboratory sample of converters is made, which with output voltages, capacitors voltages, input and output current for the proposed converters. The DC‐link (Vi) voltage is 95 with boost factor 1.6 for SCL‐qZSI, and the DC‐link voltage is 216 with boost factor 3.6 for the enhance switched‐capacitor‐inductor qZSI (ESCL‐qZSI), which confirms the relationships obtained from the proposed converters. Also, the abbreviation for this paper is shown in table 1.
