Comparative performance analysis of DC module integrated converter for photovoltaic according to various conditions

Photovoltaic DC module integrated converter topologies are various and suitability of each topology is different in actual applications. Therefore, in this paper, DC module integrated converter topology selection criteria are proposed in consideration of environmental conditions and related operation with a central power conditioning system. For this, photovoltaic systems are divided by several classifications such as a structural and an environmental. Environmental conditions are divided by photovoltaic plant, residential building integrated photovoltaic and large scale building integrated photovoltaic. According to these conditions, the performance of DC module integrated converter is analyzed regarding to operation and system design consideration. The proposed environmental suitability of DC module integrated topology is verified by simulation results.
