Buck-boost-flyback integrated converter withsingle switch to achieve high voltage gain forPV or fuel-cell applications - 2016 PROJECT TITLE :Buck-boost-flyback integrated converter withsingle switch to achieve high voltage gain forPV or fuel-cell applications - 2016ABSTRACT:This study presents a buck-boost-flyback integrated converter (BBFIC), which will intensify the voltage of photovoltaic (PV) module or fuel cell to a a lot of higher level for grid-tied applications. The converter combines 2 buck-boost converters and one flyback converter into one-stage structure with single power switch. In the ability stage, an inductor and a coupled inductor are adopted to feature buck-boost and flyback behaviours, and three capacitors are connected in series to stack up output voltage. Even though it possesses the characteristics of buck-boost and flyback converters, the matter of reversed voltage polarity is avoided and therefore the energy stored in leakage inductor can be recycled without further active clamp circuits. The structure of BBFIC can be simply expanded to get an extra-high voltage gain by stacking buck-boost cells or flyback cells. Voltage gain derivation and theoretical analysis are detailed during this study. Simulations and practical results measured from a prototype have validated the proposed BBFIC.
