Abstract. In renewable energy generation systems energy storage is needed not only to supply power when there is no generation. but also for short term smoothening of the electricity supply. The Quasi-Z-source Inverter (qZSI) allows to integrate energy storage in addition to the other energy sources mainly for output power smoothening. In the paper analysis of the scientific papers is given about this kind of converters and also theoretical and simulation based analysis of basic relations, control principles and scientific analysis that reveals limitations and passive component selection. Also the design of the proportional-resonant controller will be analyzed and discussed in more detail.

T he current and emerging investigations on Z-source/quasi-Zsource inverters (ZSIs/qZSIs) are presented. The ZSI/qZSI fulfills buck/boost capability in single-stage topology and overcomes the limits of traditional voltage source inverters (VSIs). Hence, high reliablity, high efficiency, and low cost can be achieved. The recently derived impedance networks with improved voltage gain are discussed. The classic and newly proposed modulations and feedback controls for ZSIs/qZSIs are compared. Finally, the emerging applications and trends of ZSIs/qZSIs to photovoltaic (PV) power generation are discussed. This study offers a comprehensive and systematic reference for the future development of the high-performance ZSI/qZSI.The ZSI [1] and qZSI [2] were proposed in 2003 and 2008, respectively, to overcome the barriers of traditional two-level VSIs and current source inverters (CSIs). Traditional VSIs have to perform dead time between the upper and lower switches in one bridge leg to avoid short circuit, which introduces ac output waveform distortions. On the other hand, an extra dc-dc boost converter is usually required

“…With the rapid development in renewable energy technologies, ZSI topology provides DG operators greater flexibility in interfacing the generated energy to the utility grid [143]- [145]. In [146], a new topology called quasi-ZSI (qZSI) was proposed to generate power from a PV system with a battery. The battery is shunt, with one of the capacitors in quasi-Z-source (qZS) topology instead of a DC/DC converter.…”

Recent developments in power electronics technology have spurred interest in the use of renewable energy sources as distributed generation (DG) generators. The key component in DG generators is a grid-connected inverter that serves as an effective interface between the renewable energy source and the utility grid. The multifunctional inverter (MFI) is special type of grid-connected inverter that has elicited much attention in recent years. MFIs not only generate power for DGs but also provide increased functionality through improved power quality and voltage and reactive power support; thus, the capability of the auxiliary service for the utility grid is improved. This paper presents a comprehensive review of the various MFI system configurations for single-phase (two-wire) and three-phase (three-or four-wire) systems and control strategies for the compensation of different power quality problems. The advances in practical applications and recent research on MFIs are presented through a review of nearly 200 papers.
