Abstract

In this paper, a single stage Quazi Z-Source (qZS) with active switched inductor based high gain DC-DC converter is proposed for grid-connected photovoltaic system. The active switched inductor structure contributes the additional gain factor in the existed qZS DC-DC converter. Whereas, the proposed converter possessing continuous input current and achieve the high voltage gain at lower duty ratio in a single stage. The operating principle of proposed single stage converter in shoot through and non-shoot through state with respect to characteristics waveform depicted in this article. The detail mathematical analysis with consideration of non-idealities and designing equations of active (L and C) components are derived based on the theoretical hypotheses. The proposed converter simulated in Matlab simulation software and results are validating the functionality of theoretical predictions.
