，這zhe說shuo明ming正zheng激ji式shi變bian壓ya器qi開kai關guan電dian源yuan輸shu出chu電dian壓ya的de瞬shun態tai控kong製zhi特te性xing相xiang對dui來lai說shuo比bi較jiao好hao。隻zhi有you在zai控kong製zhi開kai關guan處chu於yu關guan斷duan期qi間jian，功gong率lv輸shu出chu才cai全quan部bu由you儲chu能neng電dian感gan和he儲chu能neng電dian容rong兩liang者zhe同tong時shi提ti供gong，此ci時shi輸shu出chu電dian壓ya雖sui然ran受shou負fu載zai電dian流liu的de影ying響xiang，但dan如ru果guo儲chu能neng電dian容rong的de容rong量liang取qu得de比bi較jiao大da，負fu載zai電dian流liu對dui輸shu出chu電dian壓ya的de影ying響xiang也ye很hen小xiao。

在(zai)應(ying)用(yong)的(de)過(guo)程(cheng)中(zhong)，正(zheng)激(ji)式(shi)變(bian)壓(ya)器(qi)除(chu)了(le)具(ju)備(bei)上(shang)述(shu)優(you)勢(shi)和(he)特(te)點(dian)之(zhi)外(wai)，還(hai)有(you)一(yi)個(ge)顯(xian)著(zhu)的(de)特(te)性(xing)，那(na)就(jiu)是(shi)它(ta)的(de)負(fu)載(zai)能(neng)力(li)比(bi)較(jiao)強(qiang)
