摘要: Abstract This paper is focused on the digital implementation of a voltage and current loop for buck converter used in distributed maximum power point systems (DMPPT). It presents importance an additional control to help tracking (MPPT) algorithm. The gives detailed small signal analysis describes method compensating loop, making stability system independent operating (P-V) characteristic. also proposes original Perturb Observe (P&O) algorithm with variable step size search local maximum. calculation from slope solar panel's P-V characteristic, performances PV module. Simulation experimental results are finally provided verify performance system.
