The multi-topology converter for the solar panel

In this paper, we propose voltage converter with high efficiency over wide input voltage. This converter is suitable for the solar panel for WSN applications where the only power source is a solar cell that outputs highly variable voltage. The aim is to achieve this by using multiple converter topologies in parallel. Use of such converter has a meaning in renewable resources that in the long term operation significantly change their output voltage. The efficiency of particular topologies is estimated in simplified loss model, which is later experimentally tested.
