Now-a-days renewable energy sources like wind energy and PV arrays have more demand due to shortage of power. But the energy generated by theses sources is at low level which is not sufficient to meet the requirements of load demand. To meet the load demand high voltage gain converter is proposed in this paper. This converter employs a floating active switch to isolate energy from the PV panel when the ac module is off. With various turns-ratios of a coupled inductor, this converter attains a high voltage-conversion ratio. The operating principles and steady-state analyses for continuous, discontinuous and boundary conduction modes are described. The relationship between the voltage ratio and the duty cycle of the proposed converter is analysed. The simulation is carried out in MATLAB/Simulink Software.
