In this paper, a modified DC/DC high step up converter is proposed. Maximum power point tracking, which is very important in photovoltaic (PV) applications, is dependent on input current ripple of the PVs. In some other converters where the input current ripple is high, maximum power point cannot track properly. Therefore the proposed converter is designed based on the premise of reducing input current ripple compatible with the photovoltaic energy sources. The converter has six different modes, which are detailed in this paper. All inductor currents are illustrated and the sizing of the inductors used in the proposed structure calculated. The output voltage gain and input current ripple are investigated. The proposed converter is compared to other recent high step up converters from the angle of input current ripple. Finally, simulations are done in the PSCAD/EMTDC software package to verify the operations of the proposed converter.
