The output voltage from renewable energy sources like photovoltaic cell or array will be at low level. This must be stepped up by an order of around 20 for practical applications or grid connection. Series connection of arrays is not a viable solution. The proposed DC-DC converter topology consists of a novel single switch high gain DC-DC converter which will be a combination of coupled inductor and voltage multiplier cells (VMCs). The approach is to achieve high step up gain by using appropriate duty cycle and the turns ratio of the coupled inductor. This is done by charging the two capacitors in parallel and discharging them in series via a coupled inductor. The voltage multiplier cell operates as regenerative circuit reducing the problems with layout. These characteristics allow the operation with high efficiency and high static gain. © 2014 IEEE.
