Paper Details

As per the present scenario the power from the conventional energy sources are becoming so less (coal,lignite, oil, and gases).So most of them looking in forward for the power from green or renewable based energies likesolar, wind, tidal, biomass etc. which does not cause any pollution to the environment. There is an increasing demand forthe utilization of renewable energy sources such as PV modules. Integrating the power from the photovoltaic (PV)module into the existing power distribution infrastructure is achieved using power conditioning systems (PCS). The dc–dc conversion stage of the PCS requires a high efficient and high boost ratio dc–dc converter to increase the low dcinput voltage from the PV panel to a higher dc voltage. In this paper proposes a high boost ratio hybrid transformer DCDC converter and simulation is also performed. Lot of necessary steps want to be taken one of the main important factorthat high boost ratio DC-DC converter is needed. The proposed converter utilizes the inductive and capacitive energysimultaneously to achieve high boost ratio with the smaller sized magnetic component. This DC-DC converter utilizeshybrid switching technique. Hybrid switching consists of PWM and resonant power conversions to achieve high boostratio while maintaining high efficiency. Hence resonant operation mode is incorporated into the traditional high boostratio PWM converter; the switching losses (turn-off) are reduced, which increases the efficiency of the converter underall load conditions. The conduction losses and input current ripple are also reduced. The voltage stresses on the activeswitch and diodes are maintained at a low level.
