Hybrid Cascaded Inverter-Based Integrated Hybrid Power Supply Using Nonconventional Energy Sources

Abstract

In this research, a hybrid integrated topology that would work very well for applications involving distribution generation has been suggested. The Photovoltaic and Fuel Cell source are used to power the hybrid integrated topology's power supply. Photovoltaic source is utilized as the main power and runs very near to its Maximum Power Point, while the fuel cell section serves merely as a DC supply and feeds just the power that is needed to make up the difference. The integrated approach improves the overall power level that is supplied because of the presence of the fuel cell in parallel with the photovoltaic source. This may be achieved by smoothing out the voltage stress that are brought by the photovoltaic system's output. Another important characteristic is that the load may be fuelled by photovoltaic energy in any quantity, even if that quantity is relatively low. This is a feasible regardless of the size of the photovoltaic system. In addition, excess power may be sent to the electrolysis load, which results in the source of energy being used in the most effective manner possible. When converting voltages, a Hybrid Cascaded Multilevel Inverter (HCMI) topology is preferred over a conventional three phase inverter because it has the advantages of a gradual decrease in switching losses, a low total harmonic distortion, and a minimum power loss. This in comparison to the conventional three phase inverter, has none of these advantages. In addition to that, the voltages might be converted in a more effective way using this design. The suggested system has a number of desirable qualities, and the most notable are its low operational costs, its user-friendly layout, and its high level of durability.
