针对100W模拟光伏并网逆变器装置采样电路存在测量误差大、抗干扰能力和动态性能差等方面的问题,提出了采用基于STM32软件滤波和基于霍尔传感器采样滤波电路的双重检测方法,对电流和电压值等电气值进行采集并对数据进行可靠实时处理,并设计完成了一套实验样机,通过实验测试分析,验证了采样电路具有精度高、抗干扰能力强、动态性能好,在小功率模拟光伏并网逆变器装置设计中具有广阔的应用前景。

Aiming at the problems such as large measuring error,poor anti-interference ability,poor dynamic performance and other aspects existed in sampling circuit on the simulated photovoltaic grid-connected inverter with the power of 100W,this paper put forward the double-detection method based on STM32 software filtering and sampling filtering circuit on Hall sensor,gathered the current,voltage and other electrical values and carried out real-time processing towards the date,and meanwhile designed and completed a set of model machine for experiment.By means of experimental test and analysis,it verified that the sampling circuit is featured by high precision,strong anti-interference ability,favorable dynamic performance,and also it has extensive application...
