MISO Luo DC-DC converter for renewable energy applications

Renewable energy resources have astonishing capabilities to fulfill ever increasing future demands if utilized properly. Changing climatic conditions is a major inherent drawback associated with it and MPPT (Maximum Power Point Tracking) is one of the techniques used to overcome it (wind and solar). This paper has proposed a negative output super lift Luo converter which is integrated with multiple sources for reducing passive elements. The proposed MISO (Multiple Input Single Output) topology can be used for low or high power applications and can be extended to interface any number of sources having different characteristics. In case used for renewable sources´ grid integration, it can extract maximum power from each source with its own MPPT controller. It also has a bidirectional battery storage port that improves reliability of the system. These systems are simulated in MATLAB software environment and results are obtained.
