THD Reduction of On-Grid Solar Photovoltaic System Employing SPWM Technique

The grid-connected photovoltaic (PV) system is gaining more and more attention due to its associated abilities of uninterruptable electrical power supply. The increasing demand for sustainable energy production has led us to focus on the power electronic circuit interfaced with the renewable energy sources. To increase the efficiency of the produced solar energy, DC–DC boost converters with an advantage of maximum power point tracking (MPPT) are considered as a far-fetched solution. In this paper, a PV module with MPPT has been designed. This study also includes the design and control of inverter as well as cascaded inverter with SPWM, which helps reduce the total harmonic distortion (THD) and gives a better dynamic response and accuracy in tracking references. A comparison between different inverter topologies has been proposed here for better result analysis.
