DSP-based maximum peak power tracker using P&O algorithm

One of the common research study on solar energy is on how to improve the maximum use of solar generated power because they exhibits a nonlinear current-voltage (I-V) and power-voltage (P-V) characteristics depends on the weather changes. Generally, many methods have been introduced, known as solar maximum power point tracking (MPPT). This paper presents a study on MPPT technique namely Perturbation and Observation (P&O) implemented in Digital Signal Processor (DSP) TMS320F2812 software. The proposed system mainly comprises a dc boost converter, Siemens SP75 solar modules and DSP software and hardware. Simulation and experimental setup together with the results are shown and explained.
