In this paper, a one-stage dc-ac inverter with high boosting capability has been proposed. The proposed inverter topology develops the basic split-source inverter with a voltage-lift cell constructed from three capacitors, two inductors, and four diodes to increase the boosting capability. A relatively high voltage dc-dc boosting factor is achieved with a reduced input dc-current ripple with this combination. Consequently, this inverter topology can achieve a high voltage gain at the ac output terminals. The proposed inverter topology and its mode of operations are described in detail in this paper. In addition, the mathematical relations based on the steady-state analysis that illustrate the working principle and the main characteristics of this inverter have been introduced. Moreover, a modified space vector modulation (SVPWM) scheme is used in this paper to control the inverter switches and to reduce the input current ripples. It can be found that the proposed topology with the given SVPWM schemes increases the dc-boosting capability. The main drawback of this topology is the utilization of more passive elements in the dc-side. Three-phase SSI simulation models have been constructed and simulated using MATLAB/SIMULINK®. Finally, the simulation results are presented to validate the feasibility of this study.
