Optimization of converter design for photovoltaics with accumulation

This paper deals with the design of converter for cooperation of photovoltaic strings with accumulator. During the design, the system optimization is focused on the dimensions of the DC/DC converter, which provides the link between photovoltaics and accumulator. Design optimization of the system is based on the topology, devices and material optimization of the suggested solution whereas ensuring the required functions. The critical point of design is relatively high battery voltage at the output side of the proposed DC/DC converter and the necessity of parallel cooperation of the modules to the battery. At the end of this paper, there is 3D design of suggested solution.
