该论文提出一种无需数字信号处理的最大功率点跟踪器，采用0.35µm CMOS工艺，用于汽车屋顶光伏系统。解决了因屋顶曲率和部分阴影导致的太阳能电池最大功率点不同而能量损失的问题，通过智能模块集成模拟MPPT提升系统效率。
In the upcoming field of e-mobility roof-integrated photovoltaic systems are used to extend the cruising range of electric vehicles. Due to the roof’s curvature the solar cells (SC) show different inclination angles to the sunlight, resulting in different maximum power points (MPP) and a lower harvested energy if all SCs are controlled by a centralized MPP-regulated DC/DC converter. A further issue is partial shading. The use of smart modules where a smaller SC number is tied to a module-integrated converter with MPP tracking (MPPT) improves the system efficiency. Current smart module controllers like the SPV1020 [5] use ADCs for voltage and current measurements together with digital processing. Quasianalog MPPT methods for system-on-chip implementation in this field of application are discussed and tested [1,2] but not realized as ICs.
