A family of single-stage single-switch PV MICs with steep conversion gain

In this paper, a family of single-stage single switch photovoltaic (PV) module integrated converters (MICs) with steep voltage conversion gain capability and galvanic isolation is presented. As an illustration, the new MIC topology based on the isolated-type single-ended primary-inductor converter (Sepic) with coupled inductor is analyzed and developed. Moreover, a fast maximum power point tracking (MPPT) strategy with linear current control is adapted in the proposed SEPIC-type PV MIC Finally, a speciation of single phase 150 W prototype is constructed, and experimental results indeed verify the effectiveness of the proposed converter.
