摘要

提出了一种用于太阳能光伏(PV)能量收集的集成升压变换器的最大功率点跟踪。最大功率点跟踪(MPPT)功能是用模拟电路实现的，而不是使用微处理器。在该芯片中，通过调制升压变换器的导通时间来控制光伏模块的输出功率。该芯片采用台积电0.18 μm 1P6M混合信号CMOS工艺设计制造。总芯片面积为1.08×1.25 mm2，比微处理器小得多。测量的最大跟踪效率为90%。

An integrated boost converter with maximum power point tracking for solar photovoltaic energy harvesting

An integrated boost converter with maximum power point tracking for solar photovoltaic (PV) energy harvesting has been proposed. The maximum power point tracking (MPPT) function is realized with analog circuits, instead of using a microprocessor. In the proposed chip, the output power of the PV modules is controlled by modulating the on-time of the boost converter. The chip was designed and fabricated by using TSMC 0.18 μm 1P6M mixed-signal CMOS process. The total chip area is 1.08×1.25 mm2, which is much smaller than that with a microprocessor. The measured maximum tracking efficiency is 90%.
