The photovoltaic generator exhibits nonlinear V-I characteristics and its maximum-power point varies with solar insolation. An interleaved dual boost (IDB) converter is used to match the PV system to the load and to operate the solar cell array at maximum power point. A maximum power point tracking algorithm is developed using only load voltage information, eliminating array current detection. Analytical expressions for the PV array current and duty ratio of the converter corresponding to maximum power point operation of the solar cell array (SCA) are derived. SCA power output expressions with boost and interleaved dual boost converters are deduced. Load voltage based tracking effectiveness is demonstrated through simulation results. Experimental results validate the proposed method. Observations are also presented for partial shading conditions. The results obtained with this converter are compared with the boost converter PV system. It is demonstrated that the interleaved dual boost converter is more efficient and capable of reducing the ripple content in both source and load sides. As a result the interleaved dual boost converter photovoltaic systems require lower values of array input capacitance. SCA performance improves because of lower array ripple magnitudes
