Nine-level switched capacitor-based transformerless inverter with boosting capability for grid-tied PV applications

  • Unique Paper ID: 164318
  • PageNo: 1341-1346
  • Abstract:
  • This paper presents a new nine-phase capacitor transformerless inverter to improve the performance of grid-connected photovoltaic (PV) systems. The inverter concept has the ability to support the potential of solving the low voltage problem and making energy conversion efficient. The nine-phase topology uses a network of switched capacitors to achieve a higher voltage, thus optimizing the power output of the PV array. The design is designed to improve grid integration by reducing the use of large and expensive transformers, thus reducing overall system complexity. Simulation results and experimental verification demonstrate the effectiveness of the proposed inverter in improving energy harvesting, grid synchronization, and overall reliability in grid-connected PV applications. Research results show that the introduction of inverter-free conversion based on nine-phase switching capacitors will increase the efficiency and cost- effectiveness of grid-connected solar power systems.
