摘要： High power output may be obtained from a photovoltaic (PV) system by controlling each photovoltaic cell of a solar array individually to operate at its maximum power point. Each cell may have associated power electronics and control circuitry that may be integrated together on a chip which may be advantageously implemented in CMOS, enabling reductions in cost and size. A perturb and observe algorithm may be used to find the maximum power point by measuring the power produced at different operating points, and modifying the operating point in the direction of increased power production. In one aspect, performance of a perturb and observe algorithm may be improved in the presence of noise.

摘要翻译： 可以通过控制太阳能阵列的每个光伏电池单独地在其最大功率点操作，从光伏（PV）系统获得高功率输出。 每个单元可以具有可以集成在芯片上的相关联的功率电子器件和控制电路，其可有利地以CMOS实现，从而能够降低成本和尺寸。 扰动和观测算法可用于通过测量不同工作点产生的功率以及在增加功率生产方向上修改工作点来找到最大功率点。 在一个方面，在存在噪声的情况下可以改善扰动和观察算法的性能。
