Abstract

Shortage of power is a severe problem in rural areas of India. This work aims at providing a feasible solution to this problem. When a power outage occurs, inverters are used as a backup power source in residential applications. In general, an inverter has to go through a two-stage process for power conversion from DC to AC since a special converter is required to boost the voltage to higher level. The inverters that are used for residential purpose consume electricity from grid in order to charge or discharge the battery of the inverter that usually causes overloading. These main disadvantages can be overcome with the use of Quasi-impedance-source inverter (QZSI). With the use of a single-stage conversion circuitry for AC application, an attempt to provide a cheap and economic renewable energy system has been made in this work.
