DSP-based maximum peak power tracker using PO algorithm

摘要

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.
