“…Figure 2 shows a comparative diagram for the estimation of the pros and cons of the interleaving approach for the qZSI. The method of comparison is described in several papers [18,21]; here, we used a modified version. Five parameters were used for comparison: weighted summarized losses of transistors T L , weighted summarized losses of diodes D L , weighted inductors volume Vol L , weighted capacitors volume Vol C and the weighted cost of semiconductors.…”

This paper presents a comprehensive feasibility study of an interleaving approach for a quasi-Z-source inverter. The state-of-the-art approach revealed that an interleaving approach is often used to improve the efficiency and power density that can overcome the problem of oversized passive elements of quasi-Z-source-based converters. The focus is on the application of the interleaving approach in terms of the comparison of several important parameters of a quasi-Z-source inverter. Our analysis includes losses, capacitor and inductor sizes, as well as semiconductor costs. The theoretical comparison is based on the quasi-Z-source inverter model and the losses model. Simulation and experimental verification of theoretical statements are provided. It was found that a 40% reduction of inductor volume, along with 15–20% of efficiency improvements, are achievable. The results are discussed in the conclusion.

Increasing converter power density is a problem of topical interest. This paper discusses an interleaved approach of the efficiency increase in the buck-boost stage of an inverter with unfolding circuit in terms of losses in semiconductors, output voltage ripples and power density. Main trends in the power converter development are reviewed. A losses model was designed and used for the proposed solution to find an optimal number of interleaved cells. It describes static and dynamic losses in semiconductor switches for buck and boost mode. The presented calculation results demonstrate the efficiency of the interleaved approach for photovoltaic system. 1 kW power converter prototype was designed with two parallel dc-dc cells for experimental verification of obtained theoretical results. The experimental results confirm theoretical statements.

“…The proposed modulation method is validated though simulation and experimental results. A comprehensive comparative analysis of impedance-source based DC-DC and DC-AC converters regarding passive component count and size, range of input voltage variation, and semiconductor stress is proposed in [18]. The authors analyzed the main impedance-source converters with or without inductor coupling and with or without a transformer; useing simulations and experiments to validate this.…”
