Enhanced Flyback CCM Inverter for Voltage Stability Under non-linear Loads

Nayas Qudrathulla.P.P, P.Balaji

The photovoltaic power generation system is used widely in the residential and industrial purpose day by day. The conventional methods used for the energy conversion need to be improved due to some drawbacks. Several researches are going on in the direction of cost and efficiency, the flyback DCM inverter has been emerged out as a low cost solution. However, the flyback DCM inverter operated under continuous conduction mode shows a better efficiency at low cost. Unfortunately, it causes unintended distortions in the output voltage and current. When connected to the grid under non-linear loads conditions it cause the voltage instability. In this paper, an unfolding type H-bridge switching techniques are introduced in order to reduce those drawbacks. The simulation are done on the basis of non-linear load conditions . The output current and voltage distortions are reduced by the unfolding type H-bridge switching techniques.
