Analysis and modeling of the Quasi-Z-Source-Inverter [PDF]
IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011 This paper presents a dynamic average model of the Quasi-Z-Source Inverter (QZSI), based on the short term average values over one PWM-period, and the analysis of the possible switching states that can occur in the QZSI. The model is considerably descriptive since the modeling has been performed by analyzing the physical and functional relations with ...
