Study of Performance Enhancement Using Soft Sliding Mode Controller and Synergetic Controller for Multilevel Grid Tied Inverter

This study proposes a comparison of two control techniques for injecting regulated active power from a solar PV array to the grid and guarantees that a control strategy which is provided gives better performance in spite of the external disturbances. It includes a PV Solar Array, DC-DC Boost Converter, DC-AC Multilevel VSI and the entire system is then linked to the electrical grid through an RL filter. The control strategy using soft switching sliding mode controller has been proposed. But the only problem with this strategy is chattering phenomenon. For the complete elimination of this chattering phenomenon, a new control strategy using synergetic controller based controlling has been implemented which eliminates this chattering phenomenon and gives smooth result.
