　　風力發(fa)電(dian)機因(yin)風量不(bu)穩定，故其輸出的(de)是13～25V變(bian)(bian)(bian)(bian)化的(de)交流電(dian)，須經充(chong)電(dian)器整流，再(zai)對蓄電(dian)瓶(ping)充(chong)電(dian)，使風力發(fa)電(dian)機產生的(de)電(dian)能(neng)(neng)(neng)變(bian)(bian)(bian)(bian)成化學能(neng)(neng)(neng)。然后用有保(bao)護電(dian)路的(de)逆(ni)變(bian)(bian)(bian)(bian)電(dian)源，把電(dian)瓶(ping)里的(de)化學能(neng)(neng)(neng)轉變(bian)(bian)(bian)(bian)成交流220V市電(dian)，才能(neng)(neng)(neng)保(bao)證穩定使用。

　　通常人(ren)們(men)認為(wei)，風(feng)力(li)發電(dian)(dian)(dian)的(de)(de)功(gong)率完全由風(feng)力(li)發電(dian)(dian)(dian)機的(de)(de)功(gong)率決定，總想(xiang)選購大(da)(da)一(yi)點的(de)(de)風(feng)力(li)發電(dian)(dian)(dian)機，而這是不正確的(de)(de)。目前的(de)(de)風(feng)力(li)發電(dian)(dian)(dian)機只(zhi)是給電(dian)(dian)(dian)瓶充電(dian)(dian)(dian)，而由電(dian)(dian)(dian)瓶把電(dian)(dian)(dian)能(neng)(neng)貯存起來(lai)(lai)，人(ren)們(men)使(shi)用(yong)電(dian)(dian)(dian)功(gong)率的(de)(de)大(da)(da)小(xiao)與(yu)電(dian)(dian)(dian)瓶大(da)(da)小(xiao)有更(geng)(geng)密切的(de)(de)關系。功(gong)率的(de)(de)大(da)(da)小(xiao)更(geng)(geng)主要取決于風(feng)量的(de)(de)大(da)(da)小(xiao)，而不僅是機頭功(gong)率的(de)(de)大(da)(da)小(xiao)。在內地(di)，小(xiao)的(de)(de)風(feng)力(li)發電(dian)(dian)(dian)機會(hui)比大(da)(da)的(de)(de)更(geng)(geng)合適。因為(wei)它更(geng)(geng)容(rong)易被小(xiao)風(feng)量帶動(dong)而發電(dian)(dian)(dian)，持續(xu)不斷的(de)(de)小(xiao)風(feng)，會(hui)比一(yi)時狂風(feng)更(geng)(geng)能(neng)(neng)供給較(jiao)大(da)(da)的(de)(de)能(neng)(neng)量。當無風(feng)時人(ren)們(men)還(huan)可以正常使(shi)用(yong)風(feng)力(li)帶來(lai)(lai)的(de)(de)電(dian)(dian)(dian)能(neng)(neng)，也就是說(shuo)一(yi)臺200W風(feng)力(li)發電(dian)(dian)(dian)機也可以通過大(da)(da)電(dian)(dian)(dian)瓶與(yu)逆(ni)變器的(de)(de)配(pei)合使(shi)用(yong)，獲(huo)得500W甚至(zhi)1000W乃至(zhi)更(geng)(geng)大(da)(da)的(de)(de)功(gong)率輸(shu)出。
