| 摘 要： | 为给被测试的光伏逆变器提供一个测试其最大功率点性能的环境,设计了一种光伏模拟电源。其主要由整流滤波电路和DC/DC电源组成。整流滤波电路将交流电变成直流,开关电源部分完成降压功能,通过将输出电压采样送入误差比较器中与控制器RAM中的电压进行比较,来控制输出电流和电压,使其工作在对应的I-V曲线上。文中设计的光伏模拟电源可人为地输入温度和日照来模拟太阳能光伏曲线。

| Abstract: | In order to test the maximum power point performance of the photovoltaic inverter,this paper designs a photovoltaic analog power supply.Analog power is mainly composed of rectifier filter circuit and DC/DC power component.Rectifier filter circuit converts alternating current into DC and the switch power supply achieves the decompression function.The output voltage sampling is fed into the error comparator to be compared with the voltage across the controller RAM to control the output current and voltage for it to work in the corresponding I-Vcurve.The proposed design can simulate the solar pv curve by manually inputting temperature and sunshine intensity. |
