摘　　要：在对光伏电池输出特性及数学模型的研究基础上,用简单的方程较为精确地实现实际光伏电池I-V特性曲线的拟合。研究了光伏模拟器的方案设计,选择Buck电路作为主电路,并将电压反馈PI控制器应用到设计中。在闭环条件下,光伏模拟器仿真模型的稳态工作点与所给定的实际光伏电池I-V特性曲线相一致,证明了所提出的光伏模拟器设计方案的可行性。Based on the research of output features and mathematic module oi photovoltalc （PV） cells, a simple equation is used to fit the practical I-V characteristic curve accurately. A design of photovoltaic simulator is researched, for which a Buck circuit is used as the main circuit, and also the voltage feedback PI controller is applied. Under the closed loop condition, the steady working point of the photovoltaic simulator agrees with the given practical I-V characteristic curve, proving the practicability of the proposed design.
