Application of a new high step-up double-input converter in a novel module- integrated-inverter photovoltaic system

Grid-connected photovoltaic (GPV) using module-integrated-inverters is a well known method to use PVs in power networks. This paper proposes a novel structure of module-integrated GPV based on double input DC-DC converters. Special structure and switching strategy of the proposed converter result in high efficient power conditioning system for GPVs. The proposed structure of module-integrated GPV uses Dual-PV module(DPVM) contains two PVs. DPVM is connected to the proposed converter and the output of the converter is connected to the inverter. Two inputs of the converter assist the soft switching operation and lead to a high efficient power conditioning GPV. The proposed DPVM is presented and the application of high step up multi-input converter in DPVM is discussed. high step-up capability of the proposed converter is validated by mathematical relations. Experimental results are presented to evaluate the characteristics of the proposed converter.
