光伏并网逆变器仿真分析

硬件方案--功率板

功率板是4层板，主要功能是输出整机功率，包括直流接触器输出接口，电感连接接口，直流接触器控制电路，辅助电源，直流电压采样电路，FET输入运发电路等。主要是学习板子大电流怎么做的，以及采样电路是怎么做的。下面展示部分BOM。

硬件方案--驱动扩展板

这个板子很有意思，电路不复杂，但是板子却是6层板。可以仔细斟酌学习，为啥特意要做成6层板哦。下面展示部分BOM。

硬件方案--主控板

这个主控板是很复杂的电路方案，电路图本身20几页，PCB是4层板密密麻麻简单看一下，每个电路细节值得仔仔细细去学习。

软件方案--DSP+CPLD

软件是DSP+CPLD，这两个都是小编的软肋，大家可以自行研究学习咯。
