摘　　要：针对太阳电池的输出特性随环境变化的特点,为提高电池的输出功率和系统效率,提出一种基于固定电压法的太阳电池最大功率点跟踪(maximum power point tracker,MPPT)控制芯片的设计。其特点是采用模拟电路集成实现,具有结构简单、成本低、性能稳定等特点。芯片在1.5μmBCD(Bipolar-CMOS-DMOS)工艺下设计实现,仿真验证和芯片测试结果表明,芯片性能与设计预期基本相符。采用该芯片的太阳能供电系统能够实时跟踪太阳电池的最大功率点。Considering the fact that the output of photovoltaic （PV）panels fluctuates with changes of insolation and environmental temperature, etc. , a voltage-based maximum power point tracking controller chip was proposed to increase the output power and system efficiency of PV panels. It consists of analog modules integrated on chip and features simple structure, low cost and good stability. The chip was designed and fabricated in 1.5μm BCD technology. Simulation and test results showed that all the main performances of the chip were consistent with expectations well and the real time maximum power point tracking for system was successfully implemented.
