Abstract:
The Rеnеwablе Enеrgy Sourcеs such as Wind Energy, Fuel Cell, Uninterruptible Power Supply (UPS) and Solar Photovoltaic (PV) Systems produces DC output. By considering the above energy sources with DC, it is essential to analyze about DC-DC Converters. The DC-DC Boost Converter topologies have the demerits such as power from Renewable Sources are not transferred individually and simultaneously, Poor Electric Isolation, so not suitable for high power application, Complex construction due to more number of components and related gate driver circuits and asymmetrical structure will lead to difficult power flow control. Then, for conversion of low level DC input voltage to high level DC output voltage, Boost Converters are used. It possess continuous operation and better efficiency, due to existence of single switch. The output voltage can be stabilized by proper selection and design of input side Inductor and output side Capacitor. To optimize the performance and efficiency of the system, the correct Inverter has to be selected, for DC-AC Conversion. The coveted properties of an Inverter for efficient AC inversion are elevated Step-up and Step-down competencies and Shoot-through invulnerability. The Inverters are significantly characterized into Current Source Inverter (CSI) and Voltage Source Inverter (VSI). This paper deals with Currеnt Fеd Switchеd Invеrter (CFSI) topology, whereupon, it possess the property of elevated gain in Z-Source Inverter and enervated count o
