Due to separate<br>DC link feature DC sources can be replaced by PV module/panel and more precisely voltage is controlled. This can be<br>achieved by introducing maximum power point tracking (MPPT) in each module .the total power extracted from PV<br>panels will be maximized and hence the efficiency improves. This paper consist of single phase cascaded H-bridge MLI<br>topology is proposed for grid connected PV system and each modules is connected to one DC-DC flyback converter to<br>achieve best MPPT as well as galvanic isolation to improve efficiency. The DC-DC flyback converters are cascaded to<br>amplify the DC voltage in order to be used for medium and high voltage systems and result output voltage is used as an<br>input to H-bridge. Two MOSFET are operating in line frequency and two at switching frequency. This proposed model<br>will reduce switching losses and improve efficiency due to MLI obtain the best MPPT , get isolation at high frequency<br>eliminating the leakage current ,switching losses and voltage ripple.</p>}, number={3}, journal={International Journal of Advance Engineering and Research Development (IJAERD)}, author={Eniya.S and Diana Shally and Suresh.P}, year={2017}, month={Mar.}, pages={102–108} }
