摘　　要：为完整模拟光伏伏安输出特性中包括短路、开路状态在内的全部工作状态,提出了基于占空比比较控制的光伏模拟电源。根据CCM下Buck电路基本系统模型,设计了基于双环路的占空比比较控制策略。阐述了数字式光伏模拟电源的系统架构,分析了生成伏安曲线的数值计算方法,详细探讨了系统控制方法并制作了样机,最后使用了宽范围恒压负载验证了设计的可行性。A photovoltaic （PV） simulator with a duty cycle comparison strategy was proposed to simulate a real photovoltaic panel which was generating under all working conditions including the short circuit state and open circuit state. Based on the system model of CCM Buck converter, a first-hand duty cycle control strategy was presented. The system structure of digital PV simulator and curve fitting methods were discussed. The system control strategy was analyzed in detail and a prototype was designed. A constant voltage load with a wider range was adopted to verity the performance.
