Abstract: New single switching device converter is proposed here for extracting maximum power from multiple PV array configurations with an isolated output port. It is capable to extract maximum electrical energy from serial, parallel connected PV modules. Equivalent circuit model is derived for serial and parallel connected solar PV cell with different internal performance parameters. Different PV configuration with identical and non-identical modules is analysed. Improved P&O algorithm is developed for the proposed System. A prototype model is designed with C2000 DSP controller; a control algorithm realized in it to validate the proposed converter. Experimental results are compared with theoretical results, and its performance shows superiority of the proposed system.
Keywords: Series and Parallel Connected PV array; MPPT Algorithms; High Gain DC to DC Converter.
