Abstract
Renewable energy sources such as photovoltaic (PV) cell and fuel cell are characterized by low output voltage, strict current ripple requirement and high output current hence they require high step up gain DC-DC converter as an important interface with the power grid or distributed generation (DG) system. High gain high efficiency DC-DC converter as a power conditioning unit for a renewable energy sources is presented here. A novel high step-up dc–dc converter with coupled-inductor and voltage-doubler circuits is proposed. The coupled-inductor and voltage-doubler circuits are integrated in the proposed converter to achieve high step up voltage gain. The converter achieves high step-up voltage gain with appropriate duty ratio and low voltage stress on the power switches. Also, the energy stored in the leakage inductor of the coupled inductor can be recycled to the output. The operating principles and the steady-state analyses of the proposed converter are discussed in detail. Finally, a prototype circuit of the proposed converter is implemented in the laboratory to verify the performance of the proposed converter.
Keywords

Coupled inductor, high step-up voltage gain, voltage doubler.
