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.
