本ben文wen提ti出chu的de適shi合he於yu交jiao流liu變bian頻pin驅qu動dong的de起qi重zhong機ji械xie應ying用yong的de節jie能neng技ji術shu主zhu要yao針zhen對dui采cai用yong公gong共gong供gong電dian網wang絡luo的de起qi重zhong機ji械xie
，不bu論lun是shi通tong過guo滑hua觸chu線xian還hai是shi電dian纜lan卷juan筒tong供gong電dian均jun適shi用yong。它ta是shi從cong交jiao流liu變bian頻pin器qi的de直zhi流liu母mu線xian上shang將jiang勢shi能neng轉zhuan換huan的de電dian能neng通tong過guo一yi個ge直zhi流liu一yi交jiao流liu變bian流liu器qi回hui饋kui到dao供gong電dian網wang絡luo。這zhe種zhong技ji術shu通tong用yong性xing強qiang
，適shi合he所suo有you通tong用yong型xing變bian頻pin器qi，並bing且qie工gong程cheng實shi施shi簡jian單dan，成cheng本ben較jiao低di。
