In this paper, a new type of single-stage boost Transquasi-Z-source inverter topology is presented. The basic structure and working principle of the inverter are analyzed and its voltage gain is deduced. The model of the Trans-quasi-Z-source network is established by using Laplace transform. The dynamic characteristics of the system are analyzed, and the switching loss is explored by comparing the different shoot-through injection methods. In order to verify the dynamic boost characteristics, the Matlab/Simulink simulation is performed. Finally, the hardware circuit is built on the basis of theoretical analysis and simulation verification. The experimental results verify the feasibility and stability of the circuit.

This paper proposes a single-stage three-phase boost inverter for Photovoltaic (PV) applications. The proposed circuit topology is directly step-up the input low level DC voltage to a high-level output AC voltage in only one stage, using an inductor and six switches. A new control methodology is introduced to regulate the AC output voltage and current and is suitable for grid-connected and stand-alone applications. The proposed circuit uses only six switches of a simple type of switches that achieve the desired objectives easily without additional antiparallel diodes. The circuit topology is extensively analysed and the overall performance including total harmonic distortion (THD) is obtained by computer simulation and presented under different conditions. A DSPbased laboratory model is built to assess the proposed single-stage three-phase boost inverter when fed from a PV source. The experimental results confirm the simulation, illustrating the successful operation of the proposed circuit topology to produce three-phase AC output from the low DC voltage of the PV source.

In this study, a switched Z-source inverter with a new suitable control method is proposed that is called the series modified switched boost inverter (SM-SBI). In addition, the generalised proposed control method is presented. Furthermore, in order to show the effect of the other control methods on the operation of SM-SBI, the operation of the proposed inverter is presented using two other control methods. In order to analyse precisely, each of these three switching methods is completely introduced and then the operation of SM-SBI in these three switching methods is thoroughly stated. In addition, equivalent circuits of the SM-SBI during these control methods are presented. The voltage and current equations of all elements in the proposed structure based on the three switching methods are derived. In addition, the power loss analysis of SM-SBI is presented too. In order to show the effect of used control methods on the other conventional structures, a comprehensive comparison between the proposed inverter and the other switched step-up inverters is shown by applying these three switching methods. In the end, in order to confirm theoretical analyses, the simulation results by using PSCAD/EMTDC software are presented as well as the experimental results.
