利用540-WP光伏阵列连接阻性负载的实验装置，对增量电导(INC)最大功率点跟踪(MPPT)算法进行了评估。重点评估了两种常用的实现技术：参考电压扰动和直接占空比扰动。研究了算法参数对系统行为的影响，并计算了不同天气条件下的能量利用效率。确定了每种技术的各种优点和缺点。
This paper evaluates the incremental conductance (INC) maximum power point tracking (MPPT) algorithm using an experimental installation comprised of a 540-Wp photovoltaic array connected to a resistive load. Particular focus is given to the assessment of the two commonly utilized implementation techniques: reference voltage perturbation and direct duty ratio perturbation. The impact of algorithm parameters on system behaviour is investigated and the energy utilization efficiency is calculated for different weather conditions. The various advantages and drawbacks of each technique are identified.
