摘要：

An adaptive perturbation and observation (P&O) method for the maximum power point tracking of photo voltaic system is proposed with programmable system-on-chip firmware implementation in this paper. This proposed method holds the following merits: the control algorithm is simple and easy to implement, the power oscillation at the maximum power point and the tracking speed are improved, moreover the adaptive perturbation and observation method can track the new maximum power point rapidly when the ed to complete the boost converter circuit. Therefore, this proposed hardware structure might be the most concise circuit ever. The proposed circuit is tested and compared with the conventional P&O method. The performance of propose adaptive perturbation and observation method is 0.4 second faster and 4.9% output power higher than that of traditional P&O method.
