1、I摘要本論文所需單相正弦波SPWM逆變電源的設(shè)計(jì)采用了運(yùn)算放大器、二極管、功率場(chǎng)效應(yīng)管、電容和電阻等器件來(lái)組成電路。逆變電源是一種采用電力電子技術(shù)進(jìn)行電能變換的裝置，它從交流或直流輸入獲得穩(wěn)壓恒頻的交流輸出。通過(guò)對(duì)電路的分析，參數(shù)的確定選擇出一種最適合的方案。輸出頻率由電壓控制，波形幅值由電阻確定。本論文以SG3525驅(qū)動(dòng)芯片為核心，完成了單相正弦波SPWM逆變電源的參數(shù)設(shè)計(jì)，并利用所得結(jié)果，完成了實(shí)際電路的連接，通過(guò)調(diào)試與分析，驗(yàn)證了
