太陽能是以太陽輻射的形式從太陽獲得的能量。太陽能取決于光伏系統(tǒng)和熱力發(fā)動機。如今,這些技術(shù)廣泛專注于為并網(wǎng)系統(tǒng)和獨立負載提供可靠的電力,最大功率點跟蹤（MPPT）是光伏系統(tǒng)的重要組成部分。本文設(shè)計了一種低成本,高性能的微型太陽能逆變器,研究了將SCR全橋電路與交錯式反激有源鉗位相結(jié)合以實現(xiàn)具有220W輸出的微型太陽能逆變器,并提供整個系統(tǒng)硬件架構(gòu)和控制策略,通過實驗進行了有效驗證。在此逆變器的基礎(chǔ)上,本文設(shè)計了由太陽能光伏組件和MPPT,DC-DC Boost轉(zhuǎn)換器,DC-AC轉(zhuǎn)換器建立的模型相結(jié)合的光伏并網(wǎng)仿真系統(tǒng),并在不同的照射下（500W/m2和1000W/m 2之間）對該系統(tǒng)進行仿真。仿真結(jié)果表明,所設(shè)計的光伏并網(wǎng)仿真系統(tǒng)能夠準確跟蹤最大功率點。由于光伏陣列的轉(zhuǎn)換效率非常較低,本文根據(jù)實際情況將模糊控制的MPPT方法用于控制器設(shè)計并在低于最大功率點負載的電阻負載條件下進行測試,實驗證明和傳統(tǒng)光伏并網(wǎng)最大功率點跟蹤算法,如擾動觀測法（Perturbation and observation method）和導納增量法（Increment...
