Abstract

This paper presents the study of a new switched-inductor quasi-Z-source inverter topology (SL-QZSI) with high boost voltage. The proposed topology is derived from the old quasi-Z-source inverters by replacing of the input side inductor by two additional inductors and three diodes. This inverter has several advantages, such as, lower component ratings, a common ground with the dc source, reduced capacitors voltage stress, reduced inductors current stress, reduced diodes current stress and simplified control strategies. On the other side, the presented topology of the switched-inductor quasi-Z-source inverter allows to avoid the problem faced in the classical topology of quasi Z-source inverters caused by the inrush current at start-up, on the same time a wide range of voltage gain can be achieved to fulfil the applications which require a large gain range, especially for motor controllers and renewable energy systems. Theoretical analysis of the proposed topology voltage boost under the maximum constant boost control methods with third harmonics injection is investigated in this paper. Where, simulation results are presented to verify the proposed concept and the theoretical analysis.
