光伏并網逆變器仿真分析
硬件方案--功率板
功率板是4層板，主要功能是輸出整機功率，包括直流接觸器輸出接口，電感連接接口，直流接觸器控制電路，輔助電源，直流電壓采樣電路，FET輸入運發電路等。主要是學習板子大電流怎么做的，以及采樣電路是怎么做的。下面展示部分BOM。

硬件方案--驅動擴展板
這個板子很有意思，電路不復雜，但是板子卻是6層板。可以仔細斟酌學習，為啥特意要做成6層板哦。下面展示部分BOM。

硬件方案--主控板
這個主控板是很復雜的電路方案，電路圖本身20幾頁，PCB是4層板密密麻麻簡單看一下，每個電路細節值得仔仔細細去學習。
軟件是DSP+CPLD，這兩個都是小編的軟肋，大家可以自行研究學習咯。
