This paper presents an interleaved boost converter with coupled inductors for photovoltaic (PV) energy conversion. The proposed soft-switching boost converter uses an interleaved method to increase its power density and coupled-inductor technology to extend its step-up voltage ratio. To reduce switching losses of active switches, the proposed interleaved boost converter incorporates a synchrono...

This Paper presents Maximum Power Point Tracking (MPPT) of Photovoltaic Array under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic.

Solar energy is clean, renewable and its decentralized character is appropriate well at the scattered state of the zones with low density of population. The cost of electricity from the solar array system is more expensive than the electricity from the utility grid. So, it is necessary to operate the PV system at maximum efficiency by tracking maximum power point at any environmental condition....
