Power plays a great role wherever man lives and works. The living standard and prosperity of a nation vary directly with the increase in the use of power. The electricity requirement of the world is increasing at an alarming rate due to industrial growth, increased and extensive use of electrical gadgets. According to world energy report, we get around 80% of our energy from conventional fossil fuels like oil (36%), natural gas (21%) and coal (23%). It is well known that the time is not so far when all these sources will be completely exhausted. So, alternative sources should be used to avoid energy crisis in the nearby future. The best alternative source is Solar Energy. It has a two-stage power conversion, so power dissipation is more and due to this efficiency of the system decreases.so that we are using two-switch buck-boost (TSBB) inverter has been proposed by connecting a buck-cascaded buck-boost (BuCBB) converter in series with a line-frequency unfolding circuit, which simplify the circuit configuration and increase system efficiency. The proposed inverters have both step-up and step-down functions so that they are suitable for the applications with wide voltage-variation range. Depending on the conditions of dc input-voltage and ac output-voltage, the proposed circuits can work functionally as either buck-typed or boost-typed inverter. Due to operating with buck or boost principle, partial energy can be directly delivered to output to improve efficiency. The voltage from the Buck-Boost converter is fed to H-Bridge inverter which gives 12V AC signal that is fed as input to step up transformer to generate 230V AC which is used to turn ON the AC Induction motor.
