摘要

针对传统太阳电池分布式最大功率点跟踪（DMPPT）需要多组传感器的问题,提出一种太阳电池时分复用DMPPT设计方案和时分复用采样电路。分析时分复用电路结构与控制策略、设计直流/直流电压变换器及其PI控制参数、编写DMPPT算法,以改善光伏DMPPT系统性能。基于理论分析建立仿真模型,搭建实物模型验证理论有效性,实验结果表明：所提时分复用光伏DMPPT系统仅需一组传感器即可快速、有效地跟踪每片太阳电池的最大功率点,可有效降低DMPPT的成本。

Abstract

In addressing the issue of multiple sensor requirements in traditional photovoltaic cell distributed maximum power point tracking （DMPPT）, a design approach for photovoltaic cell time-division multiplexing （TDM） DMPPT is proposed, incorporating a TDM sampling circuit. This involves the analysis of TDM circuit structures and control strategies, the design of DC/DC converter along with their PI control parameters, and the development of MPPT algorithms aimed at improving the performance of the photovoltaic DMPPT system. Grounded in theoretical foundations, a simulation model is established and a physical prototype is constructed to validate theoretical integrity. Experimental findings indicate that the TDM photovoltaic DMPPT system achieves rapid and effective tracking of each photovoltaic cell's maximum power point using only one set of sensors, thereby significantly reducing the overall cost of DMPPT implementations.
