A Pv based Microinverter with Bidirectional Battery Charging Application in the Input Stage

Now a days increased necessity to develop and promote various renewable sources of energy for a sustainable future. A high gain converter is necessary to boost the low output voltage of renewable sources. A cascade structure consisting of a boost and buck-boost converter is equivalent to the converter structure is put forwarded. The proposed converter has a capability to produce high output voltage with decreased transformer turns ratio and elevated potential gain value. For improving volatile performance and reduction of switching loss is achieved by the help of a double closed loop control method. Also, the converter switching pulses are generated using the double closed loop control scheme. The system is effectively integrated with a solar panel. To improve the reliability of supply of the converter, a bidirectional converter with two switches is integrated with the proposed system. The cost and complexity of the system can be reduced by integrating a bridge rectifier between the high and low voltage sides. To investigate the achievement of the scheduled structure MATLAB / Simulink software has been carry out.
